Also on the Settings window, select Antivirus then select Scan and it crashes

overall too many errors to be called Retail Version going back to v10 hope that works I have read some people had problems.

Hi kalas,

When you removed BDv10 from your system, did you use the Uninstall Tool? You have to use that tool to completely remove the previous installation so you can make a 100% clean install of BDv11.

Try this solution, because it solved problems for many users.

Is not the same one as included in the menu/group BitDefender?

1.- I used the one on the menu, I did not download anything extra,
2.- Reboot the machine then proceed to the installation of BD 2008
3.- Reboot again it was fine
4.- another reboot, and all screwed up

Thanks

No, it's not the same. The Uninstall tool is a lot more aggressive and it will remove absolutely all traces of BD from your system.
When you use the normal uninstall (from Start menu or from Add/Remove software), some traces still remain (like registry keys). Those traces might conflict with other installations of BD or with other AV products that you install afterwards.

Do this:

1. Use the Uninstall Tool to remove BD from your system
2. Restart your PC
3. Install BDv11
4. Restart your PC
5. Update BD
6. Restart (if necessary)
