Hi - I tried to uninstall the Lenovo PM but then got an error - "The InstallShield Engine (iKernel.exe) could not be launched. Library not registered." 


What could this be? Any idea?

I was able to resolve this error by making a copy of "PWMTR32V.DLL" in the same folder, and then renaming it to be "PWMTR64V.DLL" and it seems to have worked.  Thanks.
