Im trying to run rx performance bench mark test SW 2015 to compare my score that i had with Win7 vs Win10   with no avail

If i run it with solidworks closed it returns nothing

Run the rx benchmark test from in solidworks and it says another session of solidworks is open.

This is how i ran the last benchmark test with win7

Anyone know why it would think another session is  open?

Or any ideas of how to make work
