# This installation package is not supported by this
# processor type. Contact your product vendor.

You can run MSINFO32.exe to check your processor architecture. The CPU type will be reported as the computer’s System Type. ARM processors may appear as ARM-based PC or ARM64-based PC. Windows Arm-based PCs FAQ – Microsoft Support

The above error denotes that you’re not using an ARM-based device.


To resolve the issue, install the x64 or x86 version (depending upon the version your program requires) of the VC++ redistributable if you’re using Windows 64-bit.

If a 64-bit program on your computer requires the VC++ runtime, install the 64-bit version.

If you’re using Windows 32-bit, download the VC++ x86 redist installer.
