I recently installed Anno 1503, Mafia, and Praetorians on my PC. After installing each one, not one of them will work leading me to believe these are not individual issues relating to each but one.

I have Steam installed but haven't used it for any of the aforementioned games.

Upon installing each one, I went into the properties of each and set them to run as admin but to no avail. When I try to launch, I'm asked to allow the program to run but nothing else happens... no error msg, nothing.

I have also

  • Restarted my PC
  • Tested other games. Fallout 3 and Morrowind still run. Rome Total War, which used to run fine, no longer works either
  • Uninstalled/Reinstalled Notepad++ as a test, and that launches fine still

Any ideas? Feel free to ask for any further info.

My PC specs:

  • Vista Home Premium (SP2) 64-bit
  • Intel Core2 Quad CPU Q8200 @ 2.33GHz
  • 8GB Ram
  • NVIDIA GeForce 9600 GT
  • DirectX 11

    Not a single one of the games you listed actually advertise Windows Vista compatibility on systemrequirementslab.com. as such, I am voting to close this question

    I'm voting to close this question as off-topic because OP is asking why their games are not working on an operating system that is not listed under the supported system for said titles. If you wish to know why these restrictions occur, perhaps super user would be a better option.

    @Timelord64 only one game is even added to that site? Also they do work on vista, see: en.wikipedia.org/wiki/Praetorians_(video_game)#Gameplay, forums.2k.com/showthread.php?24145-Mafia-On-Vista, (couldn't find anything for anno 1503)

    @Aequitas, I checked each one myself. I take systemrequirementslab over a wiki, though.

    @Timelord64 can you link me to the sys req lab site for praetorians and anno 1503, I couldn't find it. Also just because it's not listed doesn't mean it won't work

The solution to your question is quite simple. Upgrade to Windows 7, and get rid of Windows Vista.

    Why does this fix it? Why is Vista the problem?
