Since the problem occurs on multiple verisons, it is not likely an issue with the Ansys installaiton.Â
A few ideas:
 - Ansys Mechanical requires Windows scripting to be enabled.Â
 - A Firewall or Windows Defender type program is blocking AnsysFWW AnsysFW or AnsysWBU.exeÂ
 - A proxy server is being used and is interfering with the programs.Â
=================
I can help with the scripting DLLs.Â
These six DLLs must be registered for Windows scripting to work
 You must have Admin rights to register..
You can confirm registration by pasting the following into a Command Prompt As Administrator
%SYSTEMROOT%\system32\regsvr32.exe  %SYSTEMROOT%\system32\ole32.dll
%SYSTEMROOT%\system32\regsvr32.exe  %SYSTEMROOT%\system32\atl.dll
%SYSTEMROOT%\system32\regsvr32.exe  %SYSTEMROOT%\system32\oleaut32.dll
%SYSTEMROOT%\system32\regsvr32.exe  %SYSTEMROOT%\system32\scrrun.dll
%SYSTEMROOT%\system32\regsvr32.exe  %SYSTEMROOT%\system32\jscript.dll
%SYSTEMROOT%\system32\regsvr32.exe  %SYSTEMROOT%\system32\vbscript.dll
You should get six "register server succeeded" dialogs.
