Hole wizard sw2014 error after of the installation sw2015

Hi All

My Pc workstation have 2 installation Solidworks 2014 and SW2015 Beta.

If I am using SW2015 Beta at the time of modeling and using the hole wizard feature is no problem.

but if I am using SW2014 and use the same feature, SW2014 immediately crashes.

Perhaps I was wrong in setting it up, please help suggestion

Thank you
