CST 2014： Software not launching says GPU computing not supported

I am new to using CST. CST 2014 stopped while tetrahedral meshing and from then not able to launch it. Can anyone please help me what is the issue?.
Thank you.

It says Proceessing of Graphic module is not supported in 32 bit systems in CST2014.
- it may have a software fallthrough for such module instead of the HW GPU
-either it should be enabled or configured ( not familiar with CST 2014- so can't say exactly)
or the package itself is not supported without gpu.
