I installed STAAD.Pro v8i ss6 and STAAD Foundation v8i ss4 on one of our client's machine and it installed correctly. However, when I try to run STAAD Foundation v8i SS4 inside STAAD.Pro v8i SS6, it will not push through. The client said that their computer's OS is a Single Language Windows 10 OS.
So my question is: are there any compatibility issues with STAAD.Foundation v8i ss4 and Single language windows 10 OS?
I get what you are saying but you did not answer my question.
STAAD.foundation's last release was in 2011; no development has been done since then. It is a depreciated product now. This was never tested in Windows 10 OS; there is a high chance it might have some compatibility issues. If you are current in your contract, we highly recommend you to upgrade to the CONNECT version of STAAD.Pro; otherwise create a service request.
