Questa 24.3 Splash Screen, then nothing, no error or crash, just exits

[Tom_Gambill]

This is happening on two separate machines both with Windows 11, exact same behavior...Launch the app from the Questa FSE icon it installed on the desktop, it displays a QuestaSIM splash screen for a few seconds, then quietly exits.

I have verified with the License command line app that the license file is found and valid. I have also checked for debug kernel output and system logging and nothing is reported from the exe. I'm out of ideas on what to try next, I don't see anything on the internet or in this forum that anyone else is seeing this.

Any thoughts on what to try? What other information can I gather to be helpful?

Windows 11 x64, AMD 3970 threadripper CPU, 64GB RAM

Is your LM_LICENSE_FILE environment variable pointing at the license file?

[Tom_Gambill · Accepted solution]

OK,  it turns out it is the license file path. The scary dialog during installation says that you should no longer use the LM_LICENSE_FILE key, but instead set a SALT_LICENSE_FILE key. However, just setting that other key will make the license manager happy, and prevent Questa from reporting no license, but causes it to just exit after the splash screen...

I added both keys pointing to the same license file and it works now on both machines...Not sure if the SALT one is even needed, but I seem to be good now. That was very misleading...
