Hi, I'm not sure if this is the right forum for this, but any help would be appreciated. I just recently tried to uninstall a mouse driver and got the following error message: "There was a problem starting C:\Progra~2\COMMON~1\INSTAL~1\engine\6\INTEL3~1\Ctorr.dll The specified module could not be found." I followed the path, and the file wasn't there, so I downloaded a ctor.dll file, put it where it should be, then tried uninstalling again, but got this message: "The InstallShield Engine (iKernel.exe) could not be launched. Class not registered" I'm guessing somehow some of the files for InstallShield have been deleted, but can't seem to find any way to repair it. A system restore didn't solve the problem. Any help would be really great- I just want to be able to uninstall things again.
