I have two seemingly leftovers from previous programs that stop new installation of say Tuneup which crashed I removed it with Revo using advanced, and Microsoft essentials which crashed also on an update I used microsoft help and the calcs method for permission etc. I have used just about all possible available solutions that I found but non have worked..it seems there is something left over in windows installer perhaps (nothing shows for these two programs, or registry that indicates leftovers..How can I get rid of these. The programs now removed are cleaned from my system and when I search using common words for these program in registry for say tuneup, or tunup utilities I get nothing reported and still the 'removal failed' message. Anyone help please?
