I suspect that I'm out of luck on this one. However, I was wondering if there might be a way somewhere short of two seperate installations directories that I'd be able to load FSXA off of one .exe on my computer and FSX-SP2 off of another .exe. I'd like to do this because I use the Acceleration features a lot with the VRS F/A-18E and I would like to use the FSX-SP2 setup with the LDS 763 to avoid the Acceleration bugs associated with this.Assuming this is not possible, can anyone discuss some potential issues I could have making two different FSX installation directories (likely to be on the same hard drive?) where I could seperate things out this way. Is that possible at all? And if that's possible, what potential problems could I have installing things like REX in to both installations? Thanks in advance.

Acceleration bugs? :( What acceleration bugs are you referring to?

SP2 and Acceleration each use a different version of simconnect and cannot coexist in the same installation.To install multiple installations of FSX on one HD read the following post:Multiple installs of FSXRegards,Bob
