I have issues installing 5.5.2 on my PC. I am getting installer corrupt messages, regardless if I download the online or the full installer. Also updating from within the program fails.
Tried to intall using /NCRC option from within a command line.
Deinstalled system mechanic completely
Stopped all AVs
Version 5.5.1 full installer works without any issues.
Windows version is 21H1, also didn´t work with 20H2.
