When trying to load an assembly I get this error "SolidWorks encountered an error opening the document. Please contact your local SolidWorks support representative for help in troubleshooting this problem". It is a 64 bit machine. All our other machines are 32 and have never seen this issue and can also open the assembly with no issues. There have been problems in the past with this machine and I'm assuming its because its 64 bit. We are running SolidWorks 2009. The 64 dvd was used for the 64 bit.
