Can't Install Bitdefender - Incompatible with Microsoft Security Client

When I tried to install Bitdefender, it stalls at the Compatibility Check screen because it is incompatible with Microsoft Security Client. I tried the Uninstall option through the Bitdefender screen and the MSC will pop up and configure and disappear while
the Bitdefender screen just displays "Uninstalling...".

I tried the Microsoft tool for resolving install compatibility issues and Bitdefender does not show up on the list of programs for it to troubleshoot.

I contacted Bitdefender support and they said this was a Microsoft issue that they could not help me with.
