Hello people.
I have a .NET 2.0 application with nothing fancy in it. It worked until yesterday on every PC I installed or copied it to, no matter if 2.0, 3.0, 3.5 or 3.5 SP1 was installed, no matter if it was Win2000, XP or even Win7 (in total 100+ machines).
Yesterday I did my normal installation procedure and wanted to start it one time to check if everything is working...and it wasn't. The program crashed hard leaving me with the uninformative "Do you wanna report this error?" dialog. The problem is an exception in the Main(String[] args) routine of my application.
The event viewer is showing the following entry:
Event Type: ErrorEvent
Source: .NET Runtime 2.0 Error Reporting
Event Category: None
Event ID: 5000
Date: 05/05/2010
Time: 16:09:09
User: N/A
Computer: myClientPC
Description:
EventType clr20r3, P1 apomenu.exe, P2 1.4.90.53, P3 4bdedea4,
P4 system.configuration, P5 2.0.0.0, P6 4889de74, P7 1a6, P8 136,
P9 ioibmurhynrxkw0zxkyrvfn0boyyufow, P10 NIL.
Well...great information. After a lot of searching I finally was able to get further information about this exception (by adding a handler for UnhandledExceptions directly in My.MyApplication.New(), Application.Designer.vb):
System.Configuration.ConfigurationErrorsException
Configuration system failed to initialize

at MyAppNameHere.My.MyApplication.Main(String[] Args) in 17d14f5c-a337-4978-8281-53493378c1071.vb:Line 81.
And at this point I'm stuck...I'm out of ideas. I'm not using any kind of configuration system from the framework (no reference to System.Configuration, and there never was a MyAppnameHere.exe.config generated or distributed, nor have I seen this error before). I also found a bug report at Microsoft (Google Cache) about this bug (in another context, though). But as it seems, they won't even look at it.
Every help is greatly appreciated!
Edit: I'm using Visual Studio 2008 Prof.. Crash happens in Release- and Debug-Build on the client machine. Debugging the application directly on this machine is out of question I fear, 300+ Miles and they only have two computers to work with.
