I kept getting messages that the old free C Cleaner wasn't compatible with Windows. So I downloaded and installed the C Cleaner Professional v.5.55.7108 (64-bit). But when I open it, it just sits there and doesn't give me to possibility to RUN the registry cleaner, or the cleaner, as I used to do with the old free version. What's happening? Nothing? Or is it running subliminally,? Before I used to SEE what was happening, and I was shown results. Help! Tibhirine
