PROBLEM: After patching the drivers with Mobility Modder, and then Clicking on the Setup.exe icon in the ATI/SUPPORT/(software/driver version) An error message pops up stating "CATALYST install manager has stopped working" SOLUTION: This is what I found to fix the problem. (You may have to enter safe mode) 1st: Enter task manager and stop all Catalyst and ATI processes and services. 2nd: In device manager go to your display adapter and Uninstall the drivers, make sure you check the box to also delete the drivers off the computer. (otherwise they might reinstall on boot) 3rd: Download and run Microsoft Installer CleanUp Utility. With that program make sure you remove all ATI and Catalyst that show up on the list. Description of the Windows Installer CleanUp Utility <--- get it here. 4th: Download and run CCleaner make sure to clear traces of ATI and Catalyst from the Cleaner Tab and the Registry Tab. CCleaner - Home <--- get it here. *note* You may have to rerun CCleaner and Installer CleanUp a few times to make sure it gets everything. 5th: Use RegEdit and make sure that no traces of ATI remain in the registry. Fast way to find what your looking for the to use the search and Type "ATI" in quotes. I still found two items that were not cleaned by the other programs. 6th: Reboot the system, and again make sure everything is off the system. If windows detects the device and installs the PROPER (not default or generic) drivers then you messed up and will have to make sure it is all cleaned off again before rebooting. *note* Make sure no ATI folders are in the Program Files folder. I found two in there and for one I had to be in safe mode to delete. 7th. (if using Mobility Modder) follow these slightly modded 5 steps.... A: Download MSXML 6.0 from Microsoft. (Default in Vista) - Install. Step B is VISTA ONLY B: Make sure UAC control in Vista is turned off. If you don't know how to do this then read this guide (method 4 is the easiest) or click the "disable UAC" in Mobility Modder.net - please note you MUST reboot after disabling UAC. If you don't want it disabled permanently, you can turn it back on after our mobility tool has finished, but it won't mod the drivers correctly with UAC ON. C: Download the newest desktop drivers from www.ati.com (or get them from Driver Heaven Downloads). If you are using Windows XP make sure to download .net framework from Microsoft (this is built into Windows Vista so there is no need to install it). D: Run the downloaded driver, let it extract into c:/ATI/SUPPORT - but cancel the installation once the driver is extracted. E: This step will make you life easy. rename the 8-8_vista32_dd_ccc_wdm_enu_67980 (or what ever the folder name was that it extracted into) folder to something easy to type. i.e. I named mine ATI88. so it would be C:\ATI\SUPPORT\ATI88 F: Run Mobility Modder - browse to the driver in C:ATI/SUPPORT/ATI88 ( if that is the name you gave it ) - hit modify. Wait until driver is modified. 8th: THIS PART IS VERY VITAL!!! Do NOT run the setup.exe in the C:\ATI\SUPPORT\ATI88 folder. INSTEAD Open Command Prompt, CMD. 9th: Change directory to C:\ATI\SUPPORT\ATI88\BIN: cd c:\ATI\SUPPORT\ATI88\BIN 10th: Type to following command: ATISetup.exe -install -output SCREEN (you most likely will get a warning about unsigned driver. just hit yes... or OK) 11th: All should install well. you will get a page pop up telling you everything was installed successfully. If you need further clarification on anything please fill free to ask. I hope this helps. It took my about 6 hours of fumbling around to figure this out. Now it shouldn't take you guys no longer than 20 - 30 min. If that. Have a nice day.
