ERROR
When attempting to launch Ansys Workbench, Mechanical or other products, it never opens. There is no launch/loading screen. It's like nothing happens when you click the shortcut.
Do you get a loading screen?
If you do get a launch or splash or loading screen, please wait 5min. This screen can often take several min if the software can't contact a license server or is slow to do so. If it does not progress or produce an error after 5min, then this article applies.
