Tried to run it on windows 8 Pro 64.
After spending almost an hour trying to start RA 3 or RA 3 Uprising having the same issue (10 second splashscreen and then nothing), tried everything from compatibility settings to administrator rights and so fort. Nothing worked until I've tried a different approach. Turned of my antivirus's "active scanning" and "on access scanning" features and now it works.
I've also tried this on a friends computer as he had the same issue and we were trying to play together. Difference was he had no anti virus software installed so we just turned off windows defender and that did the trick for his PC.
I don't exactly know if the compatibility settings have any effect since I did not change them back when is saw that it was finally working, but just in case here they are:
- run as administrator (checked)
- run in compatibility for windows 7
Hope this helps anyone since I know how frustrating it can get.
