I have used TOCA 3 (downloaded from here) successfully on two desktop systems running WinXP Pro OEM, SP3. I also installed it (in Administrator account) on our laptop running Windows Vista Home Premium, thinking that everything had gone smoothly. That is, until I ran the game and tried to save progress after a race. Nope, didn't work. Existed Standard User account, re-entered Admin account, tried to create new profile; nope, same thing. Aaaaugh! Can't save progress = no point in playing!
Unfortunately, this bug also affects my install of Colin McRae Rally 2005. I checked with Codemasters on this problem. To their credit, they replied within a few hours, but they only said that Vista was not officially supported for either of these two games. Their advice was to check that hardware drivers were working properly under Vista and that I should try Compatibility Mode.
Anybody successfully built a career in either game under Vista?

If you installed the games to programfiles, uninstall it and install it to somewhere else like C:\Games\ or something. Then even if your on the admin account right click the shortcut of the game and go to the compatibility tab and then tick run as admin. It should hopefully save now, you could also right click it and run as admin everytime if but changing the comptibility is easier.

Thanks, I'll try that.
Can you tell me anything about the behavior of applications installed under Program Files, as opposed to anywhere else?
Also, if the games are primarily meant for my kids, how can they Run As Administrator without me having to give them the password?

Vista and to a lesser extent windows 7 have problems writing to the program files folder for security reasons. So its normally better to install games especially older games that want to save to their directorys rather then my documents elsewhere for this very reason.
To set easy administrator access to a game just rightclick the shortcut, go to properties and then the compatiblity tab and then just tick the run as admin box. I'm not sure though if you will have that option in a user profile that isn't admin as all I personally run is my 1 single admin account.
