Symptom:
After installing Rhino 4 SR9, Rhino is unable to open SOLIDWORKS part and assembly files.
Solution:
Users experiencing this problem should download
Rhino 4 SR9 Hot Fix 1.
More information:
Two files (msvcp71.dll and msvcr71.dll) were not properly installed in the same folder as the SolidWorks import plugin. This hot fix installer copies msvcp71.dll and msvcr71.dll from the "Rhinoceros 4.0\System" folder into the "Rhinoceros 4.0\Plug-ins\Import_SolidWorks" folder.
The SR9 patch installer has also been update to include this fix. Installation of SR9 using the newest SR9 patch installer or SR9 CDs should not exhibit the problem listed above.
