I would like to reinstall MSD Chemstation (ver.E.02.02). Hence I must uninstall the software at first. However, when I ran the progame as administrator Winxp compatibility, it said “Error accessing the ole registry” and the programe was still running in the background. But when the programe stopped, the software wasn't be uninstalled and it seemed nothing happened. Please tell me how to completely uninstall, thank you.
