trouble launching Abaqus CAE

Hi 

I just downloaded and installed the Student edition of Abaqus 6.4 on my laptop with Windows 10. 

I see the following when I try to launch "Abaqus CAE" from command prompt.

"Fatal Exception connectAbaqus Error: Abaqus/CAE Kernel exited with an errorPress any key to continue... "

Any idea what is causing this? I'd appreciate any help. 

Thanks!
