When I try to install ActivePerl on Windows, it says it is not supported by my processor type. My system meets the ActiveState requirements. Why is it not recognized?
This message isn't an ActiveState error message. It comes from within the Microsoft Installation tool, and it's rather misleading. The processor isn't in fact the problem.
What the message really indicates is that you are attempting to install a 64-bit binary on a 32-bit version of Windows. This won't work. A 64-bit processor will run either 32-bit or 64-bit Windows, but MSI installers for 64-bit software will only install on 64-bit Windows.
Most users solve this by using the 32-bit x86 ActivePerl installer with a 32-bit Windows, however in cases where a full 64-bit x86_64 ActivePerl is necessary there is no alternative except to first upgrade to a 64-bit version of Windows.
