I'll plan this out later today, but the major problem is that I've reinstalled Windows (3 times at least!) from the (Vista) recovery partition & the Sony Vista - Windows7 upgrade DVD, run the BD uninstall tool, & searched for/deleted all BitDefender registry keys with Regedit so I don't think any traces are left. I've tried several times to attach a summary to various (France) support log tickets (which unfortunately I've systematically deleted) & every time I got a message 'entité trop long'. Thank you SO much, it's the 1st time I've had any kind of response from anyone & this saga dates back to late February!. I've already tried to contact french support several times and have never received a reply.

If he would be kind enough to contact me I will try to provide a historic & logs then. I would really appreciate any help that Sergiu C. I have exactly the same problem & it's driving me nuts, not to mention making me very circumspect about renewing my Internet Security 2017 (n.b. Seems like recent updates are buggy and unstable on several machines. Very strange.but unless there's a quick fix, I'm moving back to ESET or AVAST.such a shame. 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.
