I just checked the link you gave. Unless your browser is quite different than mine, you should check the page again, please. On the left, ActivePerl 126.96.36.1999 -- the one we recommend. On the right, ActivePerl 188.8.131.528. Both have As and MSI versions.
And, again -- I'm still uncertain which "Win32 extensions" you speak of. Look at your installed docs; you'll see many, many Win32 extensions already installed standard, and ActiveState 5.8x is like 5.6x in that regard, I assure you.
