I haven't seen this forever.
Version of solidworks?
Simxpress? Or full simulation?
What have you changed on the system?
OS: Windows 8 64bit
Version of solidworks: SP 5.0
I dint change anything. Atleast I donno what happened. I used simulation module in my campus and just closed the laptop (without shutting down, which I generally do) and again when I tried to run the simulation module it shows this error. I am in the middle of my research work and everything got stopped since the last two days. I have tried different possible ways but failed.
what version of solidworks? 2012? 2013?
what variant of windows 8? pro?
a full uninstall/reinstalll may fix it if you made a change to your system. but there may be some other solutions depending on what version/service pack of solidworks and operating system that you're working on.
I have had this issue twice and I wish I could pinpoint the problem, but I do have a way to repair it. It is basically a wipe of all SW installation pieces and takes a couple of hours to complete. A simple repair of the install won't fix it, and a simple uninstall/reinstall will not fix it either.
I am attaching the instructions.
