Compare Exchange128 error – What is it

Some Windows 7 and Windows 8.1 users reported experiencing a Compare Exchange128 error when trying to upgrade to Windows 10. The error reads, “You can’t install Windows 10 because your processor doesn’t support CompareExchange128”. In order to upgrade to Windows 10 (64-bit), the CMPXCHG16B instruction must be present. If you receive this error, this mostly means that your CPU doesn’t have the CMPXCHG16B instruction.

Solution

Error Causes

The CompareExchange128 error normally occurs due to two possible reasons:

• CPU lacks CMPXCHG16b Instruction
• Old & Outdated BIOS – Even if your CPU has the CMPXCHG16b instruction, the CompareExchange128 issue can still occur if you have an older BIOS.

Further Information and Manual Repair

One main requirement to upgrade to Windows 10 is for your CPU to have the CMPXCHG16b instruction. You also need the right BIOS version to guarantee a smooth installation. See below on how to manually fix this issue.

NOTE: If you don’t feel confident using the manual methods listed below, it’s highly advisable to get help from an expert technician. If you don’t know someone, you can also use an automated tool to fix this.

Before performing any fixes, try to determine first if the cause of the error is due to your CPU lacking the CMPXCHG16b instruction. You can use a CPU Info tool that provides complete details about your processor, memory, and motherboard. If you’re looking for more in-depth information, you might also try command-line utilities. But, the safest and easiest way to check this is by simply searching online. Try using the search query: <CPU Model> CMPXCHG16b

Method 1 – Update your BIOS

This method will download the latest BIOS from your motherboard’s manufacturer. This makes sure your CPU has the CMPXCHG16b instruction needed to complete the Windows 10 64-bit installation. To update your computer’s BIOS, complete the following steps:

1. Determine first the current BIOS you have on your computer. Open System Information Windows app and type msinfo32 in the search bar. The BIOS version will appear under the processor speed. Record it somewhere.

2. Go to the support page of your motherboard’s manufacturer. Find if there’s any update on the BIOS that you’re currently using. If you find one, download the BIOS update file available. Make sure that you’re looking into the right model and you download all the necessary documentation. Otherwise, the BIOS update might not work.

3. Update your BIOS. Most BIOS update steps are straightforward. Just make sure to follow the steps provided.

Method 2 – Install Windows 10 32-bit version

If updating the BIOS doesn’t work, what you can do is install a 32-bit version of Windows 10 instead of the 64-bit version. Here’s how to do this:

1. Download and install the 32-bit version of Windows you currently have. If you have a Windows 7 64-bit version, get the 32-bit version of Windows 7. The same goes for Windows 8.1. When you do this, you might want to back up your files first. Remember that installing the 32-bit version works like other installations, and could delete some of your files.

2. After installing the 32-bit version, go to Updates and install all the necessary updates. This includes upgrading to Windows 10 if you’re asked to.

3. When you installed the Windows 10 upgrade, you’ll now have the Windows 10, 32-bit version installed. This will be the version activated on Microsoft servers. Despite this, the activated version stored is only applicable to your computer’s hardware, not the version of Windows 10.

4. Download Windows 10, 64-bit version.

5. Prepare an empty DVD or USB flash drive. Use Creation Media software then click the Create Installation Media for Another PC option.

6. Install the 64-bit Windows 10 version you downloaded from Step 4. Make sure not to put anything when you’re asked to input the serial number.

7. Once the installation is complete, you’ll have the 64-bit version of Windows 10.

Method 3 – Buy a new processor/motherboard

If the above two methods don’t work, there’s a great chance that this error occurs because of an outdated processor/motherboard. Your next possible solution is to buy an updated model that’s fully compatible with 64-bit Windows 10.

Method 4 – Download an automated tool

If all else fails, you might want to consider using this powerful automated tool to quickly fix the problem and any other computer-related issues.

Error Code 80240020 – What is it?

Users who receive Error Code 80240020 when attempting to install and/or upgrade to Microsoft Windows 10, are receiving the error because the Windows 10 installation folder is either corrupted or unfinished. As a result of this error code, your download and the subsequent update will not process correctly. Users who receive this code do not have to do anything specific, as it might mean that they are attempting to update before their system is ready. These users can simply wait for their computer to prompt them for the update, and then follow the on-screen instructions for the update. However, if a user is seriously wanting to update to Microsoft Windows 10 prior to the prompt, there are ways around error code 80240020. Common symptoms include:

• A dialog box appears with the Error Code 80240020
• Microsoft Windows 10 upgrade is unsuccessful or freezes in the process of updating and displays the error code message.

Solution

Error Causes

This error is only caused by one type of issue, and that is unfinished or corrupted files being present in the Windows 10 installation folder.

• Files that are unfinished in the Windows 10 installation folder are a result of the download not processing correctly, therefore the update is not successful because your computer does not have the files that it needs.
• Files that are corrupted in the Windows 10 installation folder are a result of either a faulty download or preexisting corrupted files that need to be purged.

Until your system is ready to download the new Microsoft Windows 10 upgrade, you will be unable to install the upgrade. As stated, you have the option of waiting for your system to prompt you to download (which means that your system has made the necessary changes to its own files and is ready for the upgrade), or you can use the following steps to correct the issue yourself.

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.
• After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
• Wait until the process is completed and then restart your computer.
