The type initializer for 'TDx.SmartUi.App' threw an exception

[RichardWest]

Greetings.

I have a customer that is getting the following error when launching the 3DConnexion app. "The type initializer for 'TDx.SmartUi.App' threw an exception" So far I have done the following.
Rollback windows updates that were recently installed
Uninstalled the 3DConnexion software
installed 3DxWare64_v10-8-5_r3424 from a fresh download
uninstalled .NET 4.8
installed .NET4.8
installed all Windows updates
temporarily disabled Anti-Virus software
tried logging as a Domain Admin user

None of this has resolved the issue. Along with the exception for SmartUI I also get 2 other exceptions. One for piemenus and one for LCD . All suggestions (other than wiping the drive and starting again) are welcome.

installed .NET4.8

Why version 4.8 of .NET Framework? The driver components (3DxSmartUi.exe, 3DxVirtualLCD.exe, etc) have a dependency on v. 4.7.2, not 4.8.

What operating system is your customer using? If it is a recent version of Windows 10 (or 11), then there is no need to install the .NET Framework since the required version is already included in Windows.

.NET 4.8 as they have other software that requires the current version of .NET which is 4.8. They are running Windows 10 Pro. This was working last week until the 17 Feb. Windows updates were applied that morning and the mouse stopped working. You would think that rolling back the update would correct it, but it didn't.

Check if you can find a "3DxSmartUi.log" file in %LOCALAPPDATA%\3Dconnexion\3DxWare and then share the file's content here.

have you had time to review the 3DxSmartUi.log that I shared?

Sorry for keeping you waiting but we only managed to complete the analysis yesterday.

The log didn't tell us anything. At this point, you may want to reach to our Technical Support team and have this looked at.

There was one line in the logs that caught my eye. <Device><Name>SpaceNavigator</Name><ID>ID_ProductID_C626</ID><Discontinued />
It was the discontinued part that was what I was spotting. Compared to other workstations using the exact same mouse and working, the driver version was different. The working systems had driver 10.6.4 whereas the one not working was using driver version 10.8.6. When we uninstalled the driver and installed 10.6.4, everything works.

Conclusion: The current driver does not support legacy devices. Seems like either you use old outdated drivers or make sure you have a current product. it's a shame that 3Dconnexion doesn't support older products in newer releases.

Version 10.8.6 is the very latest release and has support for the SpaceNavigator as stated here.

It would appear that you're affected by something else that changed in the driver since version 10.6.4 (released at the end of 2019).

At this point, I suggest getting in touch with our Technical Support team.

If there's SpaceNavigator hardware, only update the 3DxWare driver version to v10.8.3, no newer version should be installed if there's only SpaceNavigator, that's all.
