KB: On 32-bit Windows, why does the installer not run?

When you get an error message that the installer cannot run when trying to install on 32-bit Windows:

  • “This installation package is not supported by this processor type. Contact your product vendor.”
  • “This app can’t run on your PC. To find a version for your PC, check with the software publisher.”

A likely cause is that you are trying to run a 64-bit installer on 32-bit Windows.
