After happily using Activestate on XP for years I just installed it on Windows7. I found the problem of no write access to site/lib and have overcome that by creating a directory perl_lib and using that. I then installed a couple of modules (Mail::Send and Geo::Coordinates::UTM). The modules have installed OK and work but the documentation doesn't appear in the left panel of the Perl documentation page (C:/Program Files/Perl/html/index.html) as it did in XP.
I see that although, for example, the file C:/perl_lib/html/site/lib/Mail/Sender.html has been created, it is empty.
What is going wrong here?
I have now reinstalled Perl in its own directory C:/perl64 instead of under C:/Program Files and all problems are solved.
