My Solidworks 2018 Reader crashes on one PC but not the other. Both PC's had the s/w loaded at the same time and both are WIN7 64 bit

I upgraded the Solidworks Reader to 2018 on two PC's at the same time, both are WIN7 64 bit o/s.  On one of the PC's the Solidworks crashes after I go to Tools/Measure.  The application on the other PC works fine.  Could there be something I could check to see or change a setting on the PC with the issue?

thanks!
