Hi, this might an unusual request.
I have an older on-disk version of Malwarebytes, purchased in 2014 through Microcenter when I built my original PC. I had it on Windows 7 and it downloaded updates and kept up to date fine as recently as three months ago. Then I finally rebuilt my PC and installed Windows 10, and when I went to reinstall Malwarebytes it now gives me the error "PROGRAM_ERROR_UPDATING (0, 0, Host not found)" whenever I try to update the program from the 2012 version loaded on the disk. The program is fully authenticated with a product ID and product key, and it works just fine. The updating is the only real issue.
