Can't install Enpoint Protection on Windows 7 machine

Hello,

I'm running UTM 9.355-1, home version.    I'm trying to install the Endpoint Antivirus that comes with it the home license on a Windows 7 64 Bit system, which is fully updated.

Every time I try to install it, it thinks there is another AV installed somewhere.

I have checked and tripled check,  there is nothing.     

I've checked the add remove programs,   even the program folders on the c drive manually.   I've tried installing in Safemode,    I even checked the system with combo fix and malwarebytes and it came up clean.

Here is the Log which unfortunately doesn't tell me much, just says a 3rd party program is installed.    Any Ideas or suggestions would be helpful.  Thank you
