Guide to Resolving the Msvcr71.dll Error Code

In recent times, some Windows 10 users have seen an error code BCM20702A0, when using Bluetooth and they are concerned as to what it is all about. We can say for certain that it has something to do with your Bluetooth driver. The error message in question is:

The drivers for this device are not installed. There are no compatible drivers for this device.

The problem here tends to no longer allow specific Bluetooth components to properly communicate with your Windows 10 operating system. It also affects laptops that do not have native Bluetooth support; therefore, the manufacturer installed a dongle on the inside to deliver the service. This is not the best way to do things because native support is always better. On the other hand, maybe you’re using a Broadcom USB Bluetooth dongle that is acting up, and as such, the error is showing. Below are solutions provided for this particular error and how to eliminate it.

1. Run the Bluetooth Troubleshooter

   Press ⊞ WINDOWS to open the menu and select settings In settings choose Update & Security Go to troubleshoot and on the right panel click on additional troubleshooters Click on Bluetooth Select Run the troubleshooter, then sit back and allow the tool to do its thing. Once you’ve completed the task, click on Apply this fix if any repairs are needed Reboot your computer

2. Install Broadcom driver from official website

   Windows drivers for Broadcom Bluetooth devices are no longer posted on their website. They should be available through Microsoft’s Windows Update service. If drivers were not downloaded automatically by Windows Update, use Device Manager to refresh the driver from Windows Update. However, the Broadcom Bluetooth drivers seem to be available here on the Lenovo website. To fix the BCM20702A0 driver error, you may download and install them. After downloading it, right-click on the downloaded item, and select Run as administrator. After installation, restart your computer, then check again if it works.

3. Remove all Bluetooth drivers and USB controllers

   If previous solutions did not work, go to device manager and remove all Bluetooth devices along with all USB controllers. Reboot your computer and Windows will automatically reinstall and set all devices.

Error Code 0xC004C770 – What is it?

If the Error Code 0xC004C770 popped up on your computer during your activation of the Windows 10 software, don’t worry. This is a fairly common error, especially for people who own more than one computer upon which Windows 10 is installed and activated. The gist of this error code is that the product key that you have entered has already been claimed or used on a different computer. Because there are limitations on the number of computers that can use any given license activation code or product key, this error code can arise when you have exceeded that limit. If you have a single-use license and have already entered the particular product key onto another machine, you may see this error come up during activation.

Both Error Code 0xC004C770 and Error Code 0x803FA071 arise from the same problem and the same steps can be used to resolve both error codes.

Solution

Error Causes

Error Code 0xC004C770 is likely to appear on your screen during activation of Windows 10 if you or anyone else in your organization have already entered in the product key used on another computer.

USB storage devices are used to store small and even big files, depending on their sizes. Usually, the sizes of the USB vary from 2GB up to 16GB. And as time passes, they have advanced quite a bit and now it’s common to find USB sticks with a capacity of 32GB, 64GB, or even 128GB. And since they now have large capacities, USB storage devices are often used for storing backups of system data as well as creating an image. However, there are times when you might encounter an error message while trying to create a backup or image on your USB device. The error message states:

“The drive is not a valid backup location.”

One of the causes of this problem is that Windows was not able to recognize the USB drives as a valid backup location since USB storage devices weren’t previously large enough to store system images. To fix this error, here are some possible solutions that might help.

Option 1 – Try creating a sub-folder in the USB drive and backup all the images there

The first thing you can try to do is to create a sub-folder on your USB device. This is one good way you can bypass the USB drive limitation. How? Refer to the steps below.

• First, right-click on the USB storage device and select Format.
• Next, select NTFS as the File System and check the box next to Quick Format.
• After that, click on Start to initiate the formatting process.
• Once the formatting process is completed, open the USB drive and right-click anywhere inside its main drive window, and then select New > Folder.
• Then name the folder to be created as “Image (or anything you please)”.
• Afterward, right-click on the folder and select Properties.
• From there, go to the Sharing tab and click on Share.
• Now check if the Permission level on the System owner which should be your username is labeled as “Owner”.
• Then try to back up your files again using your USB drive while keeping the sub-folder as the backup location.

Option 2 – Update the USB Controller Drivers

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.
• Restart your PC and then click the “Search automatically for updated driver software” option.

You also have the option to update the motherboard and the USB driver from the manufacturer’s official website.

Option 3 – Run CHKDSK utility to check the drive for errors

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. To use it, follow the steps below.

• Tap the Win + S keys to open the Search box.
• Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
• After opening an elevated command prompt, copy and paste the following command and hit Enter:

CHKDSK [volume [[path] filename]] [/F] [/V] [/R] [/X] [/C] [: size]]

Note: In the command given above, “[/F]” will try to fix the system errors while “[/R]” will be the one to fix the bad sectors.

• Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
• If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.

If you suddenly find your Windows 10 computer stuck on the “Preparing to configure” screen for quite a long time now after you run Windows Update, read on as you will be guided on how you can fix that issue in this post. During an update process, there’s a lot of things that go on in the background which is why Windows Updates take quite a while before it finishes. It can be at 25%, 50%, or even 100% but the only message you’re going to see on your screen is the “Preparing to configure Windows, Don’t turn off your computer”. However, if you notice that the Windows Update is taking a longer time than it’s supposed to, the first option is to wait some more but if it’s still the same, then there’s definitely something wrong. This kind of issue occurs when Windows Update fails to configure in short correctly download and install the update. When this happens, it will revert all the changes which are why you were advised to wait for a couple of hours. There are two possibilities why your computer is stuck on the “Preparing to configure Windows, Don’t turn off your computer” screen. The first one is that the Windows 10 operating system is installing any updates. The second one is when the user profile takes time to load or encounters an error. There are several options you can try to fix the problem. You can try running System Restore or boot your computer in Safe Mode or repair the corrupted profile via Registry Editor. You might also want to try using installation media to boot and repair your computer if the other options didn’t work.

Option 1 – Perform System Restore

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Note: If you can’t boot into the desktop of your computer, you can run System Restore in the Advanced Startup Options by following these steps:

• Boot your computer into the Advanced Startup Options screen.
• From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
• Now select Troubleshoot > Advanced Options > Command Prompt.
• After that, type “rstrui” and hit Enter to execute the command which will start the System Restore process.
• Once it’s done, restart your computer.

Option 2 – Boot your computer in Safe Mode

You can try to tap the F8 key if you have it enabled in your Windows 10 computer, as you start your system to boot into Safe Mode. Once your computer is in Safe Mode, you can access the Start Menu and the Mouse and Keyboard. Aside from that, you can also access your files and other built-in tools in Windows such as Command Prompt, PowerShell, Computer Manager, Device Manager, Event Log Viewer, and many more. On the other hand, if you haven’t enabled the F8 key, you can just go to the Advanced Startup options to boot your computer into Safe Mode. Once you’re there, select Troubleshoot > Advanced Options > Startup Settings > Restart > Tap the number 4 key. After that, your computer will restart in Safe Mode. If you want to reboot into Safe Mode with Networking instead, you can tap the number 5 key and for Safe Mode with Command Prompt, tap the number 6 key. Once your computer is in Safe Mode, you can use any of the built-in tools to restore your computer or troubleshoot the problem that’s causing your computer to get stuck at the “Preparing to configure” screen.

Option 3 – Try to repair your corrupted profile via Registry

In this third option, you can try to repair the corrupted profile using the Registry but before you proceed, take note that you can only try this if you can boot into your desktop and if you can, make sure to create a System Restore Point and then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter or click OK to open the Registry Editor.
• Next, go to this registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList
• Once you’ve opened the registry key, you should see a list of all the user profiles on your computer. Now click on each S-1-5 folder and look for the “ProfileImagePath” entry and double click on it to check which user account it is related to. You will see a path like “CUsersACK” where “ACK” is the username.
• You should know which of the user account is corrupted. Just look for a key named “RefCount” and change its Value data to “0” and click OK. And if it isn’t available, simply right-click on the right pane and create it.
• After that, double click on the key named “State” and make sure that the Value data is “0” and click OK.
• Exit the Registry Editor and restart your computer to apply the changes made.

Option 4 – Try to use installation media to boot and repair your computer

Another thing you can try to resolve the issue is to use the Windows installation bootable media so you can boot and repair the operating system. To use it, follow these steps:

• You need to first create an installation media which has the dame version of the operating system installed in your computer.
• After that, once you reach the Install Windows screen, click on the “Repair your computer” link.
• Wait until the repair is completed and then shut down your computer
• Now once your computer has restarted, check if it can now boot properly.

External hard drives have become essential these days as they tend to be very useful to many users. They are usually used for storing system images like system backups, Windows installation media, or for personal use. However, if you are not able to utilize your external drivers for some reason then that could be a huge problem. One of the common issues with hard drives is when your USB device or external hard drive just keeps connecting and disconnecting. This kind of issue could be caused by a faulty USB port, some issues with the USB drivers, your computer’s Power Options, corrupted or damaged system files, and many other factors. The connecting and disconnecting issue with USB devices and external hard drives isn’t really new and has been experienced by many users for years now. Although this issue has somewhat decreased in Windows 10, there are still some users who encounter it every now and then. Worry not though for there are fixes that you can try to resolve the problem.

• After opening the Run dialog box, type “diskmgmt.msc” and hit Enter to open Disk Management.
• From there, right-click on the drive volume and select initialize disk.
• Next, select the correct partition type and proceed.

A command is not recognized Error, what it is? If you are constantly using programs like CMD or DISM directly from the Run prompt, you might have wondered how they launched instantly and how is it that the Windows operating system is able to find them right away. For instance, when you create a shortcut of a program, the shortcut knows where exactly the program is located and launches it quickly. The Windows operating system keeps a list of paths where the most common system programs are located so when you use the Run prompt, it opens easily. The list kept by Windows is called the Windows Environment Variables. If something goes wrong with this list, the programs won’t work. So in this guide, you will be guided on how you can troubleshoot the problem where any command you use is not recognized as an internal or external command, operable program, or batch file. Before you start troubleshooting the problem, you need to make sure that the program you are trying to run really exists. In fact, this can also happen to the Run program which is pulled up using the Win + R shortcut. To check, go to C:\Windows\System32 and there, check if the program exists or not or you can also try searching for the EXE in the System 32 folder. After making sure that the program exists, refer to the instructions given below.

Modify the Windows Environment Variables:

• Step 1: Tap the Win + X keys and then select System. After that, it will open the section where you can see all the properties on your computer.
• Step 2: Next, select the Advanced system setting located on the left pane and click on the Environment Variables.
• Step 3: After that, locate Path under the System Variables and select EDIT.
• Step 4: Before you edit, you need to copy the entire string and paste it into the Notepad app so that in case something went wrong, you can paste it back.
• Step 5: Next, look for the directory path, “C:\Windows\System32”. If you can’t find it, try adding a semi-colon at the end.
• Step 6: Afterwards, click OK to save the changes made and then exit.
• Step 7: Now restart your computer as all the paths are picked up when your computer restarts.

Note: Now all you have to do is to try executing the programs once again – the ones where you got the error, “ is not recognized as an internal or external command, operable program or batch file” every time you open them and then see if you can now open these programs or not.

If your USB keeps disconnecting and reconnecting after you connect your USB device on its own randomly, then the problem might have something to do with a hardware or driver issue. The first thing you have to do in such a case is to make sure that the device is working on another computer. This will help you isolate the problem and if it turns out that it works, then the problem lies in your computer and not your USB device. To fix this connection problem between your USB device and Windows 10 computer, you can use the options given below as a reference.

Option 1 – Update or reinstall the Universal Serial Bus Controller driver

Since it could be a driver issue, you can try to update or reinstall the Universal Serial Bus Controller drivers using the Device Manager. Refer to the following steps:

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.

Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.

• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 2 – Try to change the USB port

You might want to change the USB port since modern computers have a variety of USB ports. So if your USB drive supports USB 3.0 or 3.1, make sure that you plug it inside a USB 3.0 or 3.1 ports. If you’re not sure which port, just keep in mind that the USB 3 port is usually blue or you can also use your computer’s documentation or manual as a reference to locate it.

Option 3 – Try to turn off the Power Saving option

You could also try to turn off the Power Saving option to resolve the problem. All you have to do is switch to Power Management after you select the Properties of the USB device and from there, uncheck the “Allow the computer to turn off the device to save power” option. On the other hand, if you are using a laptop and did not use the USB device for a long time, then it could be powered off. This will ensure that the system does not turn off the USB device.

Option 4 – Try to reinstall the latest Universal Serial Bus controller drivers in Compatibility Mode

In this post, we will discuss what the “ bootres.dll ” file is in the Windows 10 operating system and where it’s also located. In addition, you will also be guided on how you can replace or fix a corrupt bootres.dll file which may prevent you from booting to your Windows desktop and will display an error message instead saying, “Boot critical file resourcescustombootres.dll is corrupt”. There are times when this error might also boot your PC to the Automatic Repair screen. DLL files, also known as Dynamic Link Libraries are external parts of applications that run on Windows as well as other operating systems. Almost all applications are not complete in themselves and store code in different files so if there is a need for the code, the related file being called by a certain application is loaded into memory and used. If the software or the operating system is unable to find the concerned DLL file or if the DLL file ends up getting corrupted, you will most likely get an error message. In case you don’t know, the bootres.dll file is a critical system OS file, size 90KB, and can be found in the Windows folder. It is a part of the Boot Resource Library and portrays an important role in making sure that your PC boots properly. So if it ends up getting corrupted, your PC may fail to boot correctly and you’ll get an error message instead. To resolve this problem, here are some suggestions that might help. If your PC automatically boots to the Automatic Repair screen, you need to click on that option to run the Automatic Repair. If it doesn’t work, you have to boot into the Advanced Startup options to manually access and run the Automatic Repair. Once you’re in the Advanced Options, you will be able to:

• Run Automatic Repair
• Use System Restore
• Start Windows from an external device
• Access Command Prompt
• And use the System Image Recovery to restore Windows from a Factory image.

If the Automatic Repair fails to fix the problem, you may have to use System Restore or the Command Prompt to carry out further troubleshooting steps. Refer to the guide below to use these tools.

Option 1 – Try running the System File Checker in Safe Mode

Running the System File Checker is the safest way to fix DLL file missing or corrupted errors are thrown up by the Windows operating system as it could give you better results. System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files that might be causing the Machine Check Exception BSOD error. To run the SFC command, follow the steps given below.

• Boot your PC into Safe Mode.
• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 2 – Try running the DISM tool to repair the System Image

To repair the System Image, you need to use the DISM or Deployment Imaging and Servicing Management tool. The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:

• Open the Command Prompt as admin.
• Then type in this command: Dism /Online /Cleanup-Image /RestoreHealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Note: The command you executed will check for Windows component store corruption and will restore its good health. The scan might take up to 15 minutes. Once it is done, you have to restart your computer.

Option 3 – Try to repair the MBR and rebuild BCD

To repair the MBR and rebuild BCD, follow these steps: The problem might boil down to the Master Boot Records since the previous case has already been isolated.

SD memory cards have surfaced as standard cards for digital cameras and microSD as phone standard memory cards. Most people have and use at least one daily, so naturally copying files and even formatting SD cards is a natural thing to do, but what if you cannot copy files or format SD cards? Fear not because we had this issue and tried several things in order to overcome the problem and after some time here is a list of what can you do if you are facing this exact issue. The list is written from most simple solutions to more complex ones and it is advisable to follow it as presented. That being said, let's dive into solving the problem.

1. Remove Write Protection on SD card

First and in my experience the most usual thing preventing deleting, copying files, and formating SD card is due to write protection. Take an SD card out of the laptop, camera, or card reader and visually inspect it. On side of almost every SD card, there is a hardware lock switch and mark where it needs to be positioned in order to be locked. Even if the switch is positioned on unlocked state, switch it to locked and then back to unlocked. Sometimes this easy moving of switch can resolve some contact issues and the card will start working normally. Another type of lock that could be turned ON is a software one. If for any kind of reason data protection has been turned ON, you will need to turn it off in order to be able to format an SD card. In order to do this follow this guide:

1. Press ⊞ WINDOWS + R to open the Run dialog
2. In run dialog type in diskpart and press ENTER
3. Once diskpart is opened in command prompt type in: list disk and press ENTER
4. Locate your SD card and type in select disk x, where x is disk number followed by ENTER
5. After the SD card is selected type in: attributes disk clear read-only and press ENTER

This process will clear the software lock on the SD card, after following this method try to format the card again, if the problem still exists go to the next solution.

2. Format SD card using Command prompt

Command prompt is a great tool and can perform some commands that are not been able to be completed using file explorer or another tool inside Windows.

1. In the taskbar search box, search for cmd and select the Command prompt
2. On the right part select run as administrator
3. If needed click on YES on UAC prompt
4. Inside command prompt type in diskpart and press ENTER
5. type in list disk followed by ENTER
6. Select your SD card by locating its number in the list and typing select disk X, where is X SD cards number in list and press ENTER
7. Once SD card is selected type in format fs=ntfs quick and press ENTER

This should format SD card but if for reason even this step is provided as unproductive, go to the next solution.

3. Format your card with the Disk Management tool

1. Go into the taskbar and search for Disk Management and open it
2. Select SD card partition that you wish to format
3. Right-click on the partition and select format
4. After the format is done, enter the volume label, file system, and allocation unit size. Confirm with OK
5. Press OK again to confirm the formatting process.

If you have not managed to format your SD card even with this method go to the next solution.

4. Repartition card with Disk part

If all previous solutions have failed there is a chance that the SD card has bad sectors on it. If this is the case that we will need to partition cards in order to isolate bad sectors and use healthy ones.

1. Press ⊞ WINDOWS + R to open the Run dialog
2. In run dialog type in diskpart and press ENTER
3. Once diskpart is opened in command prompt type in: list disk and press ENTER
4. Locate your SD card and type in select disk x, where x is disk number followed by ENTER
5. Type in Clean and press ENTER
6. Type in Create partition primary and press ENTER
7. To select a new partition type select partition 1 followed by ENTER
8. Make partition active by typing active and pressing ENTER
9. Format the drive by typing format fs=ntfs label=SDCard quick followed with ENTER
10. Assign a letter to drive by typing assign letter=h followed with ENTER
11. Type exit to close Command prompt followed again by ENTER and open File Explorer to check if the drive is active

5. Try a dedicated SD card formating fool

If anything failed so far, one last thing you could do is to download and try a dedicated SD card formatting tool. One that I would recommend is SD Memory Card Formatter, which is free software make specifically for formatting SD memory cards.
