Steam Compatibility issue..

[Craftable124]

Not sure if I should ask this here but I can't find any steam support articles.

 

When in the steam properties, I'm set to compatibility for windows vista. I'm locked to it because the drop-down and checkbox are disabled. Whenever I launch Big Picture I get an error, and GTA IV won't launch. GTA says I need SP1 to run on Vista, because steam is in vista compatibility mode. How do I disable compatibility or get GTA to work? Otherwise it's a waste of $10... Thanks.

1: Exit steam

2: Open the properties for the steam.exe

3: Go in the compatibility tab

4: Uncheck all compatibility boxes

5: Apply

6: Right click run as admin (just to be sure, otherwise you can disregard this step)

7: Try launching the game again

 

Hope this helps,

Greets.

No the problem is the windows compatibility checkbox is disabled, so I can't disable Vista compatibility. It's locked to that.

Than check the box and change it to Win 7

But if Steam starts in compatibility mode, it will tell at start-up

Deleting those registry files fixed the compatibility issue, but GTA IV still doesn't launch. It has no error code this time. I'll mark this as solved and look elsewhere.
