Microsoft Visual C++ Runtime Library Error

Fix Microsoft Visual C++ Runtime Library Error, Microsoft Windows operating system supports a form of shared libraries that are known as DLL (Dynamic-link libraries). These are also known as code libraries that are used by multiple processes while one copy is loaded into memory. Runtimes are also code libraries that are loaded by applications when the application is called to run on the system. The most common runtime libraries that are used today are Visual C++ Runtime Library and Java Runtime Environment. These libraries are practically used for nearly every single application you run on your system. Therefore it is very important that these libraries are in good working order. Microsoft Visual C++ Runtime Library Error occurs when this runtime library becomes corrupted. When Microsoft Visual C++ Runtime Library Error occurs, the applications powered by this runtime library fail to run smoothly, resulting in locking you out of those applications and hampering your ability to work on them. Generally speaking, this error indicates system instability and poor PC maintenance. If this error is not fixed timely it can expose your system to serious PC damages like system freeze, crashes, and data loss.

Solution

Error Causes

Microsoft Visual C++ Runtime Library Error is triggered for numerous reasons. These include:

• Poor program installation
• Disk fragmentation
• Missing and damaged .dll files
• Registry corruption
• Malware invasion

In a nutshell, it can be said that the deep-rooted cause of the Microsoft Visual C++ Runtime Library Error is the registry. All the causes listed above are associated with the registry. For simplification, the registry is the main database of your system that stores all the activities executed on the computer in the RAM, the hard disk. This includes both the important data and junk files such as temporary files, internet history, bad registry keys, invalid registry entries, and also the files from the uninstalled programs. If these files are not removed from the registry frequently, it overloads the hard disk and leads to obscure error message displays on your system like the Microsoft Visual C++ Runtime Library Error as warning signs. Sometimes, rebooting the system may fix the Microsoft Visual C++ Runtime Library Error. However, this is temporary. Error message pops again after some time. So, instead of seeking out a temporary solution, it is advisable to look for a solution that can repair this error for the longest time.

We are all waiting for the release of Intel’s Alder Lake series of processors and real-world results on its performance. Sadly lately it came to our attention that some games might have issues with the processor. Now before you go on the bandwagon on bashing Intel itself take note that it is not Intel’s fault at all. The issue that arises is mostly due to DRM software and how it works. As you might know or not, Alder Lake has two sets of cores, standard performance cores, and power cores, and with Intel’s Thread Director on-chip right cores will be used for the right tasks, and here lies the issue. DRM software might detect Thread Director as something suspicious and malicious, and then cut access to the game because of this. Intel, of course, has reached DRM manufacturers and places documentation about how software should be developed with this hybrid technology in mind. Of course, newer games will be updated if needed and everything will work fine, also games on GOG will work fine because of GOG’s policy of no DRM store but some older ones might be left in limbo. They could work fine but DRM might be triggered and prevent them from loading, usually, game developer itself removes DRM protection after some time but that is not really always the case and there is a chance that some games might simply just not work on Alder Lake CPU only because of DRM protection.

Conclusion

I will admit that I have not been a great fan of DRM in general, I understand that game developer want to protect themselves from piracy but how it looks they were not really successful with it. Even today single-player games get pirated on the day they are released and legally bought ones always make trouble for people that actually paid for them. I remember times when DRM was awful and you could install a game a limited number of times, luckily this was removed but it seems that many old habits still remain sadly and DRM is present even today in various forms. GOG is proof that people will buy DRM-free games and that they will support this kind of model. Maybe it is time to forget about fighting against piracy, you will not make it go away and people who do not want to buy games will not buy them, on other hand many users that do buy games, if they cannot use them they will rest to pirated version since that one will work. It is sad to see that pirated software can work better than a legal one and offer a more pleasant experience.

If your Microsoft Edge browser encountered a Stop Error that says, “INVALID_POINTER_READ_c0000005 (atidxx64.dll)” in your Windows 10 computer, then this indicates that your Graphics card driver is outdated. According to security experts, Microsoft has already acknowledged the problem and stated that this issue exists with Windows 10 v1809, Windows Server 2019, and Windows Server version 1809. Although there is no direct way to resolve the problem, there are still some workarounds you can try. If you are using a RadeonHD2000 or HD4000 series video card, the update will be blocked for you. Some users also claim to experience performance issues with the lock screen or the ShellExperienceHost. However, if you are using AMD, the problem is that it no longer supports Radeon HD2000 and HD4000 series graphics processing units or GPUs. Even though Microsoft is already working for a way to resolve the problem, here are some alternative solutions you can check out:

Option 1 – Update your Graphics card drivers

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.

Option 2 – Try removing AMD Radeon HD2000 and HD4000 drivers

Although this is not exactly a perfect solution, removing AMD drivers will make the operating system fall back to the default GPU available on your motherboard. You also have the option to completely disable the hardware.

• Tap the Win + X + M keys to open the Device Manager.
• Next, look for your Graphics card drive, and under Display Adapters, right click on them and click Uninstall device or Disable device.
• After that, restart your computer. This will disable the AMD drivers so you won’t be able to find them. It will also release the Windows 10 v1809 update on your computer and in case your operating system tries to prompt you with the “New Device found” message, simply ignore it.

Option 3 – Try to use another browser

You might want to use another browser especially when you already updated your computer and Microsoft Edge still keeps on crashing. You can use Google Chrome, Mozilla Firefox, and other browsers as alternatives until you sort out the problem.

Option 4 – Try to remove the Graphics card physically

You might also want to try removing both AMD Radeon HD2000 and HD4000 as they are very old graphics cards. And since AMD is not going to roll out anything, at least on its own if your motherboard has an onboard GPU, it would be best to get rid of the cards. After that, install the Windows v1809 update and then put them back in. You also have the option to install the driver but just don’t use Microsoft Edge.

Recently, some users reported that they were unable to access a website and only got the Error 1005 Access Denied instead. Specifically, users experience this issue when trying to open the Crunchyroll website – one of the largest anime and manga websites. This particular error is encountered not just on Crunchyroll but on a variety of websites like blogs, video streaming, forums, and so on. Here’s the full context of the error message:

“Error 1005 Access Denied – The owner of this website has banned the autonomous system number (ASN) your IP address from accessing this website.”

Usually, this error occurs when the website administrator decides to block an IP address or IP range. To fix this error, here are some suggestions you can try:

Option 1 – Uninstall the VPN service you are using or use a different provider

If you are using a VPN service, you might want to uninstall it. As mentioned, website administrator blocks IP ranges if they notice any malicious activities and because of this, your IP address might fall into the banned range even if you didn’t do anything at all. To uninstall the VPN service, follow the steps below.

• Tap the Win + R keys to open the Run dialog box
• Then type “appwiz.cpl” in the field and hit Enter to open the Programs and Features in Control Panel.
• From there, look for the VPN service you are using, select it and then click on Uninstall to remove it.
• After that, restart your computer and try to install the latest version of the program again. It should work now. If not, proceed to the next available option below.

Option 2 – Try disabling the Proxy server

There are some users who reported that they’ve fixed the problem after they’ve disabled the use of a proxy server using the built-in way. Follow the steps below to disable proxy server.

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

Option 3 – Use the Google Public DNS

You might want to change your DNS to Google Public DNS as it could also help you in fixing the ERR_CERT_COMMON_NAME_INVALID error in Chrome. To do so, follow the steps below.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 4 – Try contacting the website administrator

If the first three given options didn’t work, you might want to consider contacting the website administrator especially if you’ve already determined that the issue does not occur due to a VPN or proxy server that you’re using. This option can be quite tricky since you won’t be able to submit a contact form since you’re banned from accessing the website but you can contact the admin via the form section if available.

Internet connectivity issues like Can’t connect to this network present a complex problem with simple solutions for PC and laptop users. First, it is usually recommended that users rule out problems with the internet connection, router, and Wi-Fi settings before proceeding to troubleshoot settings on your PC/laptop. Once the rest are ruled out, we can then proceed with the following troubleshooting steps and guidelines to fix your wifi connection issue: The first step is to update your windows network adapter driver. Connectivity problems may arise if your network driver is not updated or if it is incompatible with the network adapter. To do so, you may resort to any third-party driver scanning and installing programs found online. This solution should resort if users don’t want the hassle of perusing through windows settings that users may not be familiar with. However, this solution requires a pre-existing internet connection other than wifi, so it is recommended you have a backup internet connection via ethernet. The second step is to uninstall the driver for your network adapter. This solution is to resort if there is an issue with the driver as restarting the PC after the following steps let windows reinstall the driver again:

• Open the quick access menu on your keyboard by pressing the Windows key and X key at the same time and select “Device Manager” from the menu list.
• From the list of devices, select “Network Adapters”
• Usually on the top of the list is the Wireless Network Adapter
• Right-click the Wireless Network Adapter and select the option to “Uninstall device”
• You will be given a confirmation in a new separate window to proceed. Click “Uninstall” to proceed.
• After completing the previous steps, try rebooting your Windows PC and reconnecting to see if it works.

A third step is to disable the 802.1 1n modes of your network adapter by following the next steps:

• First press the Windows logo key and the X key at the same time to bring up the quick-access menu. And like the previous step, select “Device Manager”
• From the list of devices, select “Network Adapters”
• Right-click the Wireless Network Adapter from the drop-down menu and select properties
• Under properties, select the “Advanced” tab then select the 802.1 1n Mode. To the right drop-down menu change the option to  “Disabled” and click “Ok”
• After, try to re-establish the connection to see if the steps have worked.

In the event that any of the preceding did not fix your problem, it helps to take a second look at the router and network settings using the interface provided by your ISP. A simple reset to the back of your router often fixes the issue. Also, try to check if you have any other administrative capabilities over the network to determine whether your device, in particular, has been MAC filtered or if the frequency of your wireless adapter is not compatible with the broadcast frequency of your router.
