I reinstalled FS2004.
The application file is here: F:\Flight Simulator 9\fs9.exe
The shortcut properties, and every other place I check says Run as administrator. I have applied that to all users (just to be sure)
I have full permissions, and am system administrator.
No matter whether I click on the shortcut, or on the exe file in Explorer, I get UAC asking if I want to let this unknown publisher make changes to my computer [MS W7 doesn't know that MS published FS9??]
I click YES
The little blue circle rotates for about 4 or 5 seconds, then disappears. Task Manager confirms that no applications are running.
I tried with Disc 4 in the CD drawer. No difference.
I couldn't discover which Version I had, so I d/l SP1, which ran and congratulated now updated to 9.1
No difference.

Any tips, please?
