Hi All,

I installed SolidWorks 2013 Beta3 and found the same issue on my machine when looking at equations in SolidWorks 2012 SP04. Looking at our SPR database this has already been reported with the critical SPR# 667457 – "Instability with equations after installing SolidWorks 2013 beta 3 and SolidWorks 2012 on same computer."

The workaround which worked for me is to repair the installation of SolidWorks 2012 from the Windows Control Panel.

As a gentle reminder, this is accessed from Control Panel>Programs and Features and Right Mouse Button click on SolidWorks 2012 and choose ‘Change’. You can then work through the Installation Manager to repair the current installation of SolidWorks 2012.

Had to repare installation to correct problem...

Now SW2012 works as expected.
