Was told my ticket would be escalated, but never received any follow-up emails. Tried talking with tech support, but no assistance there. There appears to be no way of getting a new install. I tried the manual uninstall download/links from bitdefender website, but that doesn't clear whatever is preventing the reinstall. I tried uninstalling and reinstalling several times, with reboots, with the same error message. From Control Panel uninstall screen, it appears that bitdefender agent reinstalls, but that bitdefender does not. On another computer, I uninstalled bitdefender and bitdefender agent from control panel, but when I tried to reinstall, the reinstall would download a 320MB file, then unpack files for install, then give an error message that I was protected and bitdefender is already installed. On one computer, I uninstalled bitdefender and bitdefender agent from control panel and reinstalled, without a problem. Recently, bitdefender would not go active upon start-up on several computers. Running a Win 7 (64) system and had bitdefender running fine for several months on several computers.
