Nothing happens when I press the solver button.

I have just moved my seat of SW2018 Premium SP5.0 to a new machine.  I have opened an existing part to complete a Static FEA study.  The study previously worked on the old machine, however when I try to run the solver nothing happens.  I have tried a installation repair and have also created a test part, again nothing happens when I try to run the solver.  Any ideas?

Thanks Neil.
