Windows operates on what is called the .NET Framework. The current version is 4.5 but the zSpace Edu Server requires version 3.5 which is not enabled by default in Windows 8.1 or Windows 10.
If the .NET Framework 3.5 is not enabled the zSpace Edu Server Windows service will be in a stopped state. If you try to start it you will see an error message "The operation could not be completed."
To check and if needed enable .NET Framework 3.5 do the following:
- Click the Windows Start button and type "control panel" without the quote marks. Click the Control Panel in your search results.
