Either there are two issues or one big issue with your systems as DM/Mesh usually don't have the same issue as CFX-Pre/Post
Do you use VPN ?
Can you ping the hostname of your machine ?
Can you try newer version of ANSYS ?
For CFX issue, you can try renaming C:Users
For DM/Mesh issue,
1. Manually register the DLLs listed below by starting a Command Prompt (DOS) with "run as administrator" , then typing:
regsvr32.exe ole32.dll
regsvr32.exe atl.dll
regsvr32.exe oleaut32.dll
regsvr32.exe scrrun.dll
regsvr32.exe jscript.dll
regsvr32.exe vbscript.dll
make sure they all say succeed
2. Check the PATH System Variable to make sure that C:WINDOWSsystem32;C:WINDOWS;C:WINDOWSSystem32Wbem;… entries are in front of everything else.
Like: PATH=C:WINDOWSsystem32;C:WINDOWS;C:WINDOWSSystem32Wbem;…all other entries...
Thanks,
