What operating system are you using?
What OpenSees version?

• This is my computer properties

• This is the OpenSees-solvers

It works normally on other computers, but not on this one. Could you help me solve it? Thank you very much.

It should work on Windows 10.

Make sure hydra_pmi_proxy.exe and mpiexec.hydra.exe (in C:\OpenSees-Solvers\bin) are allowed by the firewall.
Make sure the antivirus is not blocking anything in C:\OpenSees-Solvers.
If you are not sure, download again the OpenSees-Solver installer, disable the antivirus, and install it again

It should work on Windows 10.

You mean WIN10pro is unable to use?
I shut down the firewall and antivirus on the WIN10pro, The same problem arises.

I mean that it should work without any problem on Windows 10. We only had some known issues with Windows 7.

Did you try to re-install OpenSees-Solvers while the antivirus is OFF?

Yes I did. In fact, it worked fine the first time I used it on my workstation, but when I used it again a week later, I found this error.

Well this is strange, it means something happened during that week. probably some new software or some windows settings?

Hi! Did you manage to solve the problem in Windows 7? I am having the same error but using window 7

What is exactly your issue?
