Hello again Scott!
Bitdefender has been in the market for a shorter period of time but has advanced to be a really great antivirus for Windows. We compile the list of 100% working codes which can be copy-pasted to redeem active subscription till December 2021. Press the Windows Key and the R key together on your keyboard. Type appwiz.cpl in the command box that appears and press Enter.
I downloaded the Bitdefender Total Security 2013 installation kit from your email, 64-bit link, which appears in my Downloads. It didn't give me the option to save it, as you suggested. When I open it and click on 'Continue' - I get the message that Bitdefender cannot uninstall MSE automatically, and that I must do it manually. I just bought a Dell 8930; Intel i7-9700; RTX 2060 6 gb; Win 10 64 bit and immediately ran into an issue trying to run Bitdefender VPN Premium. I had no problem running Bitdefender VPN on my old HP Desktop and it still works fine on my Asus laptop. I am hard-wired to my router and the internet si.
The error you mention is usually indicative of driver remnants from a previous Bitdefender installation, or perhaps even from another AV solution (you can use sc delete driver_name from cmd as admin, then reboot). The first step we recommend is to run the Endpoint Security Uninstall Tool while in Safe Mode. Once the tool completes and you reboot, try the installation once more.
If the install still fails with the same error, please generate a Support Tool log and submit it to our Support Team for review, using our online Contact Customer Care form. Be sure to include details such as the exact error message received, and be sure to mention that you already tried booting into Safe Mode and running the Uninstall Tool.
The Support Tool can be downloaded from the Help & Support section of the Bitdefender Control Center console, or from the following links:
