OptiStruct doesn't start


good afternoon,
I have the student version of Altair Hyperworks 2017 and I have a problem with Optistruct. I can create the mesh ( a simple shell of four elements) with all contrains, materials, etc. the problem is when I try to start Optistruct from the menu analysis-->optistruct: I save the fem model in the correct folder and then using analysis as a run option I press Optistruct. The software creates the fem file but it doesn't start Optistruct. Is there a solution?
Thanks for answers

Hi,
Are you using Student Edition?
Could you please share operating system details?
Can you reinstall and check if that helps?


Hi,
sorry for the delay. Yes, I am using Student Edition. I've tried unistalling 2017 version and installing 14.0 but the problem still remains.
Operating system details:
Windows 7 64 bit
Intel Core i7-2670QM @ 2.20GHz
RAM: 16 GB
Thank you very much for any help.


Hi,
Can you change the working directory and try again?
Does it happen with different models?
I am struggling with the same problem. In the working folder I have .hm, .fem, .tcl and .cfg files only. Anybody can help us?
