Previous post about this problem. Followed recommendation from Pat Willener and have tried all the options offered. I still cannot install and do not see where I can submit Cleaner log file. Have run Microsoft Fixit to help with install and uninstall. I do not have enough courage to tackle registry files like QUID and SQUID files in registry, because I do not know what I am doing or what parameters are needed, or what I can really mess up in the process.
