I've installed ansys 11 sp1 to ms vista x64. i've successfully cracked the products, and then installed the CFX. Designmodeller, analysys works great, but when i start advanced cfd, I get a message: CFX-pre terminated while attempting to connect workbench. Has anybody any idea, what to in this situation? before it, i used xp 32bit, and it has worked.
sorry for my english, thanks!

On a Windows 64-bit machine it is expected that the 64-bit versions of Workbench and CFX would be installed; the issue being seen is due to having installed the 32-bit versions.

The workaround for this is to set the variable CFX_FORCE_WOW64 to the value 1. This has to be set as a regular environment variable (using Control Panel > System > Advanced tab > Environment Variables button > System Variables list > New) as its value needs to be known before perl is run at the launch of CFX.
