Hey,

So I tried to install my old loved Grand Prix 4 on my Windows 7 32bit. Installation was done in 2 minutes.

After patching it, and starting it up, everything seemed to work fine.

After setting everything up, and launching a race, something horrible happened.

It crashed at loading the race! This normally happened at XP after screwing your GP4 up, and you'd need to reinstall. But at Win7 this failure keeps happening and I can't seem to find a solution.

Used dear old fella Google to search for solutions, but nothing helped.

Does any of you have a clue on how to get this beauty to work?

Tried with XP compatibility?

Yes, even 98 compatibility

you sure it installed correctly? 2 minutes seems awefully short

Try setting the affinity of GP4.exe process to one core only.

Can't do that.
I am administrator, but for some reason it tells me I don't have the rights to do this.

I think you have to run the Task Manager as admin or disable UAC. You can run Task Manager as admin by creating a shortcut to C:\Windows\taskmgr.exe (or wherever it is), rightclick it and select "Run as administrator".
I had GP4 on my old box with P4 HT and setting affinity to one virtual core only reduced crashes a lot.

Such problem happens with NASCAR 2k3, and it has solution: http://www.addictivetips.com/w ... able-it-in-windows-vista/
disable this thingy. Everything worked for me as it worked before, just I could run N2K3

Helped for NR2003, did not help for GP4
It still crashes whilst loading a race

Have you tried a GPxPatch? IIRC it can do quite useful things with GP4 including setting the affinity to one CPU only.
