I'm trying to add a NYPD car to GTA IV going through Spark IV but comes up with this error:

The process cannot access the file C:\Program Files (x86)\Rockstar

Games\Grand Theft Auto IV\pc\models\cdimages\vehicles.img

because it is being used by another process.

But I've only got one Spark IV open.

Please HELP!!.

did you run GTA IV on the same time? or was it doing an update?

none

I use GTA Vehicle Mod Installer V1.2. try using that. It bypasses all the SparkIV stuff & installs it in less then 5 seconds

Thanks, But now I have another problem I had installed SparkIV and that didn't work so uninstalled it but now GTA IV doesn't seem to work, well you can get into the

but when it automatically loads a save game it comes up with and error well it says

Grand Theft Auto has stopped working, windows is trying to fix the problem etc etc.

Can you help me?

Did you installed SparkIV inside the GTA IV folder? I hope not. That may be why GTA IV has now stopped responding. Now I would say uninstall and reinstall GTA IV, update it to 1.0.7, download SparkIV v0.6.9(beta) or later, install it within its own folder, do not create that folder inside the GTA one.

Thanks might have to reinstall it again. Already down that for other problems. Thanks for helping.
