Issue Summary

The Wisenet Device Manager (WDM) application sometimes lags upon launch on Windows 11. This article describes the possible causes of this issue, as well as how to keep the WDM from hanging upon launch. 

Resolution

Wisenet Device Manager fails to open on deployed Windows 11 systems because the system security baseline enables FIPS cryptography enforcement. Wisenet startup uses .NET RijndaelManaged, which throws a FIPS-related InvalidOperationException. The application runs but never displays the UI. Adding the .NET AppContext switch UseLegacyFipsThrow=false to Wisenet Device Manager.exe.config resolves the startup failure without disabling FIPS globally.

To add the switch: 

1. Navigate to C:\Program Files (x86)\Wisenet\Wisenet Device Manager.
    

2. Edit the file Wisenet Device Manager.exe.config.
    

3. Locate <runtime>.
   
   
    

4. Add a new line and paste this:
   
   <AppContextSwitchOverrides value="Switch.System.Security.Cryptography.UseLegacyFipsThrow=false" />
   
   
    

5. Save the file.
