try download this one, and see if u guys can patch or not
GRID1.2Patch_Fixed_Installer.exe"This is the proper way to install the 1.2 fixed patch".
1) Download the Grid 1.2 Fixed Patch. Click here to download:
Grid 1.2 Fixed Installation Patch (http://www.vanwinterswyk.com/gridfix/GRID1.2Patch_Fixed_Installer.exe)
2) Go to My Documents. Copy the Codemasters folder and back it up. An easy way to do this is to make a new folder in My Documents titled "GRID Backup Game" or something so you won't forget. Copy and paste the Codemasters folder into this new folder.
3) Open Control Panel and go to Add/Remove Programs. Locate GRID and uninstall. If for some reason the game will not uninstall, a manual uninstallation is required. How to manually uninstall? Go to your GRID directory and delete the folder. After this, reinstall the game in the same place you deleted it from. This will keep the registry entries the same and prevent a double entry. Attempt to uninstall again.
If you do know how to clean registries, search for Codemasters and delete everything for GRID. Only do this if you are 100% sure you know what you are doing. If you are not certain as to how to exactly do this, stay with the previous steps.
4) Insert the GRID DVD and install the game.
5) Now install the GRID1.2patch_fixed.exe and select the directory you have installed GRID to. The installation of this fixed patch must be to the GRID root directory (the folder with GRID.exe).
6)After Installing the Game and the 1.2 fixed Installation Patch, Place the Codmaster folder with the Backup you made in My Documents
Don. Play Game and have fun!!!!
