[OFFER] Adobe After Effects 5.5 (2001)
This is not a complete dump; this is actually taken from a warez compilation and as such, all non-English files have been stripped away. I am offering this because early versions of After Effects for Windows are somewhat rare compared to other Adobe products from that era.
I believe that this is compatible with Windows 98 and up, and maybe NT4 SP4/5/6+. Other Adobe creative products had dropped Windows 95 support by then so I assume that After Effects would be in the same boat.
I installed it on Windows 2000 and it works fine.
