Mesh Editor does not have a valid license ??

Mesh Editor does not have a valid license ??

(OP)
Hello all,
I am trying to run the student version of ANSYS 17.2 on my personal computer, and every time I try to add a mesh to my geometry the mesh editor crashes and the following massages appear:

Error ! The Meshing editor does not have a valid license.
Warning
Unable to initialize addins in Meshing. Either the application crashed or Workbench lost communication with it (No connection could be made because the target machine actively refused it 127.0.0.1:xxxxx).

My key specs. are:
Windows 10
Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz, 2601 Mhz, 4 Core(s), 8 Logical Processor(s)
16 GB RAM
NVIDIA GTX 960M

I have already tried the following:
Double checked the environmental variable pointing at the license file
Created a new environmental variable ANS_OLD_ATTACH = 1
Ran the "product and CAD configuration 17.2 .exe" and installed all required prerequisites
Uninstalling and reinstalling.
Installing a previous version (16.2).
Installing using elevated administrator account.
Disabled anti-virus, fire-wall.
Disabled IPv6.

Please Help !!!!
