I want to use this unsupported add-in but do not want chance damaging my SolidWorks or Windows installation.

If someone has tried this add-in I would like to hear from them.

Will the MathCAD add-in for SolidWorks work with MathCAD 14 and SolidWorks 2013 x64?

Are there any unpleasant side effects?

Are any esoteric procedures required to make it work?

If so, what procedures?

Does the Mathcad_15.dll work for MathCAD 15 and 14 or only 15? There is also and older Mathcad_14.dll available for download.

In addition:

The provided MSWord file supplied with the MathCAD Add-in says to register the dll file "Mathcad_15.dll";

but what do you do with all these other supplied files?

Interop.SldWorks.dll

Interop.SwConst.dll

Interop.SWPublished.dll

Mathcad_15.tlb

Mathcad_15.xml
