The licensing key for our Student products is built into the download, so if you've followed the installation instructions correctly you shouldn't see such an error - This indicates that your license file hasn't been identified/and or you've inadvertently installed the ANSYS License Manager. If you have other any other versions of ANSYS product installed, or a very early version of the Student Product (Release 17.2 or earlier) then you will likely have the full ANSYS license manager installed.

To correct this problem you need to uninstall the license manager and the R19.0 ANSYS Student product, reboot your machine, then re-install the ANSYS Student R19.0 Product. See here for the solution, scroll down the thread to see Peter Newman's verified answer.

Uninstall all ANSYS from the computer.

You have to extract the files from the zip file for ANSYS Student 19.0 into a folder on your C: drive.

In Windows Explorer, type %AppData% in the path field. You will be in the Roaming directory. Delete the Ansys folder, then go up a level and down to the Local directory and delete that Ansys folder too. Finally, if there is any Ansys folders under C:\Program Files, delete those.

After uninstalling all ANSYS, manually use regedit to delete:


Restart your computer. If you can turn off your anti-virus during the installation, that may help.

After that, you have to find setup.exe in that folder and right click and "Run as adminstrator".

 If nothing is working then installing a fresh OS copy might be a better solution for such case.

To confirm, are you referring to the Windows10 OS or Ansys OS?

Windows7 OR 10
