You mean to tell me that's how the version 5.6 is displayed? Lol. Great. So if I decide to install 5.10+ and I want to have that as the active version I can go through the steps of installing activestate's version and simply add an entry in the environment path variable as well as the script that handles .pl scripts in IIS? Then I can just remove whatever entries are there for 5.6 in the path and the reference in IIS? I'm guessing this will require an unfortunate reboot? Thanks for the info.
