I did a search of the support help topics as well as the whole C-130 forum and could not find and answer to my problem. I installed all the C-130s and was going to use ACE but for some reason I got this error.
After clicking ok the exe is deleted from the ACE folder in Flight sim. I am running Windows Vista Home Premium 64bit SP2. I did install them running it as an admin. I have this problem on the C-130, AC-130, CL-130 and the 707, but for some reason my F-104 works fine. Does anyone have any ideas what might be causing this?

Thanks in advance for your help
