Just updated to 18.104.22.168 of Registry Mechanic today. When installing, it (NOD32) seems to block the creation of Update.exe in the installation folder and also indicates (after the install) that there were suspicious files found. However, these files were both in the temp folders as a result of the install. If I turn off AMON before the install it works fine (the install). RM 5.1 seems to work OK even after the error msgs during the install, so the install seems to have worked OK. But I'm sure this is a FP. I have submitted the files (as requested by NOD32) already to Eset. Yeah, signatures and program are uptodate, BTW.
