Learning Forum

[din_hn]

I have checked the forums and have not found a viable solution yet. One of the people has the same problem as me under this forum for 'ANSYS Products', but I couldn't understand how they solved it because it seems they are using Linux and I use Windows. Another person with the same problem as me in the forum for 'ANSYS Free Student Softwares' has their posts replied, but I couldn't access it because it denies me even opening the page. My last solution is to make a new post myself.

So...I downloaded ANSYS Free Student Software to learn Workbench and Fluent. Fluent and the other applications work well, and I have no problems opening them except for Workbench alone. Whenever I open the workbench, the same unexpected error comes up no matter what I do.

It loads all the plugins, initializes then instant error.

"Unexpected error: The type initializer for 'Ansys.Core.Expressions.ExpressionEvaluator' threw an exception."

The same error over and over again. How can I get my work done at this rate? Then, whenever I open the 'Show Details' button. This is what comes up.

An unexpected error has occurred: The type initializer for 'Ansys.Core.Expressions.ExpressionEvaluator' threw an exception.

Solutions I tried:

1. Reinstalled 5 times to be exact.
2. Redownloaded the software from the website and then reinstalled it.
3. Restarting my computer.
4. Checking my environment paths, and they linked correctly.

All the above solutions were done, and not a single one worked. I am annoyed. I want to contact support but cannot, and it directs me to this because I have the student software. Can someone help me?

If you Open windows file explorer and go to:
%APPDATA%\
You should see a directory named:   Ansys
rename this to Ansys.old.
now try to run.

If that doesnt help:
What is the output from opening a DOS cmd prompt and typing in the following and hitting enter:
set

[din_hn]

I tried renaming the directory, which has the same problem mentioned above.

As for the output from running 'set' in cmd, it gives the following prompt:

It could be that IronRuby is interferring.

I would try editing your system PATH to make sure that it starts with c:\Windows\system32

Path=C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Windows\System32\OpenSSH\;C:\Program Files\NVIDIA Corporation\NVIDIA NvDLISR;C:\Program Files\Microsoft SQL Server\Client SDK\ODBC\110\Tools\Binn\;C:\Program Files (x86)\Microsoft SQL Server\120\Tools\Binn\;C:\Program Files\Microsoft SQL Server\120\Tools\Binn\;C:\Program Files\Microsoft SQL Server\120\DTS\Binn\;C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\;C:\Program Files (x86)\IronRuby 1.1\bin;C:\Program Files\dotnet\;C:\Users\Din_H\AppData\Local\Microsoft\WindowsApps;C:\Program Files (x86)\Common Files\Oracle\Java\javapath;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;....etc

Also, if IronRuby is not needed, you can try uninstalling it.

After carefully following your suggestions, I edited the path similar to what you have shown, and the error persisted. But after IronRuby was uninstalled, only then did the workbench work properly.

Thank you. It finally works after days of trying.
