Hello, Upon building a new PC, I installed Aida64 for diagnostic purposes. It's the trial version 6.32.5600. Much to my chagrin, it appears that Aida64 cannot be closed (it immediately reopens itself) and it even cannot be uninstalled (as the uninstaller leave aida64.exe at c:/Program Files (x86)/FinalWire/AIDA64 Extreme/, and this executable will keep opening itself). Any ideas, how to get rid of this befaviour? Thank you & regards.
