Ansys can't open it, what should I do?

The most common problem is the license plate. The most direct and simple solution is to delete the registry, reinstall the license, and then there should be no problem.

(1) Open the registry, find the following items (the third item may not be available), delete and restart the machine;

HKEY _ local _ machine \ system \ controlset001\ services \ ANSYS, Inc. License Manager

HKEY _ Local _ Machine \ System \ ControlSet 002 \ Services \ ANSYS, Inc. License Manager

HKEY _ Local _ Machine \ System \ Current Control Set \ Services \ ANSYS, Inc. License Manager

(2) Open setup.exe, follow the tutorial, and reinstall Step 3, icense, ok!

After reloading the license in this way, there will be no more problems.
