Hi , I am using the 12.0 version, Vista 32 bit. When I try to run the Workbench I only get error message: "system.nullreferenceexception object reference not set to an instance of an object. in Ans.UI.SplashScreen.ReturnError(String image Path) ..... " . ICEM and CFX Launcher are working properly. Does someone know where could be problem ?

Did you find the cause of the problem? Can you now successfully install on Vista?

This error can be caused by running an OpenGL graphics driver which is not compatible with your current Ansys version. With 12.0 I fixed it by downgrading to an eralier version of my graphics driver.

However myself I am now also getting it with 12.1 with the officially certified driver as soon as I try to open the Engineering Toolbox window....

We've given up with Vista, luckily our installations for Ansys 12.1 are now only done on machines with XP. I presume Windows 7 can only be better than Vista.....

I was able to fix the problem.
The page at

http://ati.amd.com/products/workstat...erators.html#2

lists 8.634 as the most recent certified release for Ansys 12, but it didn't work.

I donwgraded to the older certified release 8.543.1.3 and the problem went away!

Very sensitive to OpenGL version obviously...
