In this case, to resolve the issue at hand, you need to check system architecture, and then download and run the appropriate package installer for your system.

3] Run Installer in Compatibility Mode

Even though it’s stated on the installer error prompt that the redistributable package in question can only be installed on Windows XP SP1 (x64) and newer platforms, it’s possible that for some reason the Windows 11/10 system is detecting the installer as old program, and as such creating a conflict. In this case, you can Clean Boot your system, and then, in that state, run the package installer in Compatibility Mode and see if the error is fixed.

To run the package installer in Compatibility Mode on your PC, do the following:

• Open File Explorer.
• Locate and right-click the redistributable package executable (installer) file.
• Choose Properties.
• Navigate to the Compatibility tab.
• Now, check the Run this program in compatibility mode for option.
• Choose Windows 7 or 8 from the drop-down menu.
• Check the Run this program as an administrator option.
• Click Apply > OK.

Now, check if the issue is resolved. If not, you can run the Program Compatibility Troubleshooter and see if that resolves the issue.

Hope this helps!
