Questa FPGA Starter edition License issue.

I am trying to launch Questa, but im getting the following error within cmd:

C:\altera\24.1std\questa_fse\win64>vsim -c
** Fatal: Failed to initialize licensing environment. License environment not set correctly.
Unable to checkout a license. Vsim is closing.
** Error: Invalid license environment. Application closing.

I have followed intels guidance found here:

https://www.intel.com/content/www/us/en/docs/programmable/683472/25-1/and-software-license.html

I have added systems variables and checked that that the license can be found using:

C:\altera\24.1std\questa_fse\win64>echo %SALT_LICENSE_FILE%
C:\altera\24.1std\questa_fse\licenses\license.dat

When I launch questa, I get the siemens splash screen and then the application silently fails.

Please could someone help me with this?
