On Win7 I installed AP 5.24 then found I had to use 5.22. So I uninstalled 5.24 (unused) and installed ActivePerl-5.22.2.2202-MSWin32-x86-64int-300560.exe. When I ran my perl script from the command line I received an error that perl524.dll was missing. I don't know what is still looking for perl524. This is when I searched the registry and found no dlls were registered. I did find some 'perl' entries that did point to the AP folder.
I also found that I have perl5 in Git and Anaconda on this PC.
Is AP not compatible with these?
