Both my workstation and my laptop computer have been experiencing stability problems over the past 3-4 months. Typically not witih SolidWorks, but a lot with Internet Explorer. The error message always points to a problem with an Adobe product. So, I thought it might be a good idea to allow Adobe to "update" my Adobe software in hopes of curing the problem. After updating, Acrobat would no longer even load up, citing a massive failure of the licensing system. As it turned out, my copy of Adobe Acrobat Pro Extended was a counterfeit. I have yet to receive my new copy, but wonder if any others have had a similar issue. And most importantly, it could be that other fake applications could cause problems with SolidWorks, just like it seems to do with IE.
