AFAIK there are many circumstances where the old AvsP won't run, and have to use the mod version. So I installed it in my Windows 7.

But I try to run it I get a message saying "error loading Avisynth", which it is installed.

What I wonder is if it's not looking for Avisynth on a different place, as I install all my video related programs on a "Video" folder.

Should I install Avisynth in Program Files (86)?
