I should explain more what happened I guess.
1. I downloaded Home, tried a boot scan, I got that error, so I un-installed.
2. I re-downloaded Home and tried again, same error. Un-installed.
3. I downloaded Pro, tried and got the same error. This time I didn't uninstall.
4. I did a normal scan, and it scanned.
So yea Idk why it wont boot scan. Or really what the error means.
