Entering NPVR "Settings" results in unhandled exception

[hypnos]

I had a stable install of NPVR 2.03 on XP SP3 for several months and just recently encountered errors regarding the starting of the recording service. I decided to update to 2.15 and encountered problems with the install (NextPVR.exe -upgrade, NRecord.exe INSTALL). I followed the uninstall instructions found in the posts (deleting program file dir, public dir, scrubbing registry), stripped back the .net installs, reinstalled .net 2.0 and the prerequisites. Install of 2.15 went well. Rebooted and the recording service and Ntray start. I launched NPVR and went to settings. Clicking on Devices throws an unhandled exception and the Device Setup button does not bring up its screen. Same thing happens when I select Channels. All other setting options bring up their screens. The logs and error messages are attached. Any thoughts? Am I just missing something? I've repeated this uninstall/reinstall process 3 times with the same result.

It doesn't look like this is directly a NextPVR problem, so reinstalling is unlikely to

It looks like something is broken with the database components of your .NET install. Unfortunately I'm not really sure what you'd have to do to fix this.

Googling "The type initializer for 'System.Transactions.Diagnostics.DiagnosticTrace' threw an exception" returns quite a few hits, and I'm sure the answer is in one of these.

Sub, thanks for the reply and insight. That was my fear that it was something deeper with the .NET install. I'll try your recommendation. They keep mentioning app.config so I'll see where it leads. Thanks again.

Managed to get it sorted out. Searching Google for the error gave nothing of use, so I dug into the .NET installs. There was a cascade of errors from 2.0 through 3.5. Uninstallers wouldn't work so had to go at it manually. Found a useful tool for removing all aspects of a given .NET install. Google "dotnetfx_cleanup_tool.zip" for the program. Stripped everything down to .NET 1.1 and built back up in selective startup. NPVR install & config went without issue. Thanks again for your efforts.

Great - glad you got it sorted.
