Our lab has two PCs with ANSYS licenses and on one PC the Q3D analysis works, and on the other the Q3D analysis doesn't work. Hopefully this narrows down the problem. The computer which it works on is a Win10 machine. The computer which it does not work on is a Win7 machine.
On both computers I am able to render a Q3D design but on the Windows 7 machne, when I do Setup->Analyze the solver immediately aborts and I get the message that I should contact the ANSYS support (see attached screengrab). This problem persists even when I load one of the standard example designs for Q3D (see attached screengrab viamodel.PNG). I found this example design in this folder:

My question is: Does Q3D not work on Windows 7?June 25, 2021 at 11:17 amANSYS_MMadoreAnsys EmployeeTechnically Windows 7 is not supported with 20.1. Could you please paste the screenshot into a message, rather than attaching? We are not permitted to download attachments. Could you also please let me know if this was working on this machine previously? Please also go to Tools -> Options -> General Options -> General -> Directories and paste a screenshot of that screen?

June 25, 2021 at 7:16 pmANSYS_MMadoreAnsys EmployeeIs this the basic via_gsg example project, or have you made modifications to it before attempting to solve? If you've made modifications, please try solving just the example as is, without modifying any of the project settings.
June 25, 2021 at 7:18 pmsarafsSubscriberIt is the basic via_gsg project with no modifications whatsoever made to it.
June 25, 2021 at 7:21 pmANSYS_MMadoreAnsys EmployeeCan you try changing the Temp directory in your Tools -> Options -> General Options -> General -> Directories to something like C:\Temp, and make sure you have a C:\Temp and see if that has any impact?
June 25, 2021 at 7:24 pmsarafsSubscriberwhen I did this, the same error shown in the screenshot above persisted.
June 25, 2021 at 7:26 pmANSYS_MMadoreAnsys EmployeeDid you exit AEDT and restart it after making the change?
June 25, 2021 at 7:28 pmANSYS_MMadoreAnsys EmployeeYou may also try updating your graphics driver from the vendor's website and rebooting the machine.
June 25, 2021 at 7:30 pmsarafsSubscriberYes I just tried that and the error persisted.
June 25, 2021 at 7:39 pmsarafsSubscriberI don't think its the graphics driver because it is up to date.
June 29, 2021 at 3:42 pmANSYS_MMadoreAnsys EmployeeThis issue could well be related to Windows 7 which isn't supported. I'd recommend trying to run on a supported platform such as Windows 10. You can find our platform support information here: https://www.ansys.com/it-solutions/platform-support
