Problem launching Inspire and HyperMesh 2026.1 on Windows 11

Carlo03

Hello,

I'm using the Altair Student Bundle Edition on Windows 11, and I'm having problems opening both Inspire and HyperMesh 2026.1.

Both programs worked fine at first, but after a few days they started showing errors and stopped opening correctly.

I tried reinstalling Inspire using both the standard installer and the Alternate Installer, but the problem is still there.

I checked Windows Event Viewer and found several CodeIntegrity errors (Event ID 3077). These errors show that Windows is blocking some Altair DLL files, including hwtypes.dll, vtkImagingCore-pv6.0.dll and hwfdmplugincore.dll. In some cases, Windows also reports that the publisher cannot be verified.

Smart App Control is enabled on my PC. It seems that Windows security is preventing these files from loading, but I'm not sure why, especially since both programs worked before. I haven't disabled Smart App Control because Windows warns that I might not be able to enable it again without resetting or reinstalling Windows.

I also tried installing Inspire in a separate folder using the Alternate Installer, but I still get the same type of error.

Could you help me understand what is causing this issue and how I can fix it without disabling Smart App Control?

I can send screenshots of the error messages and Event Viewer logs if needed.

Thank you for your help.
