Hi,

This issue may occur because of Environmental variable so please refer the below solution link,

You can set or remove certain paths from your environment variable in windows as fallows,

1) Open Control Panel --> Systems --> Advanced system settings --> 'Advanced' Tab --> Environment variables--> Under System variables

2) Look for Path(QUARTUS_ROOTDIR) and click 'Edit'

3) Either set it correct version or remove

please let me know how it works for you.
