How to initiate Ansys12 from NX6

[NXsupport]

Hi,

I want to initiate Ansys 12.1 workbench from NX6.. Currently I have Ansys11 and Ansys12 on my system along with NX6.. On the menu bar, I have Ansys 11.0.. Iam unable to change it to show Ansys 12.1 , which when clicked initiates Ansys12.1 workbench.

Suggestions please

Thanks

You might need to unregister and reregister the two dlls that control that menu. The two batch files to do this will be located in a path like:
<Ansys Install Location>\v120\AISOL\CAD Integration\UnigraphicsNX6\winx64\startup
(replace winx64 with intel if you are on a 32 bit system)
Also, check to make sure that the WB 12.1 integration is supported from NX 6. It may not be.
