For others who come across this,

This user had other Ansys Student products installed. Thermal Desktop doesn't install in the same folder by default. We re-installed Thermal Desktop and Sinda/Fluint in C:\Program Files\ANSYS Inc\ANSYS Student\... and everything seemed to work after that.

We will investigate why this was happening and make sure the product is set up to work when Ansys Student products are also installed.
