Hello, As Marcos requested, I'm starting a new topic to troubleshoot 12.2.30 to 13.2.18 version upgrade on two my computers. I've recently purchased a license and tried to install the latest NOD32. Right after the installation, antivirus GUI crashed multiple times. Initial scan didn't complete and NOD32 service crashed. Exactly the same issue happened on my second workstation running under Windows 10 2004.
