in thread Tkx not installing properly

The available releases of ActiveTcl 8.6 Community Edition for Windows are all 64-bit, while DWIM Perl for Windows is 32-bit. So I think you're right that this issue is due to a bitness mismatch, and a 64-bit Perl distribution (e.g. Strawberry or ActivePerl) would be needed instead.
