AVG Error Code 0xc0070643

Solution 1: Fix 0xc0070643 using AVG tools

Solution 2: Download and install the offline version of AVG (Standalone Installation)

Another method is to use the AVG offline installation. This program uses an online installation that downloads the necessary files as you install the application. Consequently, the installer is very lightweight. However, this process can be faulty. If there is any problem with the connection or with AVG servers then the installation may fail. To avoid this problem, it is recommended that you try to use the installer offline. The file is much larger and takes longer to download. However, it is likely that you will avoid this error. You can find this file in the AVG download section. Or download it from a reliable third party source.

Solution 3: Delete AVG entries from the registry.

It is likely that AVG cannot be installed because of traces in the registry from a previous installation. Therefore, it is necessary to remove this instance manually. Therefore, it is necessary to open the Windows Registry Editor. With this in mind, press the Win+R combination and run the following command:


Then paste this address into the bar.


Please right-click on any AVG record. Please delete it.

Finally, close the registry and try to install AVG again.

Solution 4: Check permissions

Sometimes, the 0xc0070643 error can occur if you do not have the necessary permissions to access the installation folder. In fact, certain permissions are required to complete the process. In fact, it is necessary to allow total control over the folder. Please remember to apply these parameters to the installation folder. If you want to know how to do it, I invite you to see our post.

Solution 5: Disable all other antivirus/firewall tools

Perhaps you can think of what else is synonymous with better. However, sometimes it is not advisable to combine several antivirus solutions on the computer. In fact, these tools can interfere with each other. And what is worse, they can prevent AVG from being installed correctly. Therefore, it is recommended to uninstall any security app before installing AVG antivirus.

Solution 6: Make sure you have the necessary requirements

It is necessary to have Visual C++ installed to complete the AVG installation. Indeed, some users have reported this error, related to the Visual C ++ Redistributable for Visual Studio 2012 Update 4 package. Consequently, the solution is to go to the Microsoft website and download the latest version of the file.

Solution 7: Make sure you have enough space on your installation unit

It is likely that this error is caused by lack of storage in the C drive. That is, on the drive where AVG will be installed. That’s why the solution is to free up space. In fact, it is essential to have at least 4 GB of free disk storage space. This way you can avoid errors and complete the installation successfully.
