Exception occurs when opening Options
Issue #16
resolved
When opening the options windows I get an error. Additionally, I cannot save my settings, even in Admin mode. Each time I re-open the savings the last changes are gone. I cannot find the options XML saved anywhere on my computer.
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

That is really odd. I do not get much information from the crash log unfortunately. The settings XML will be in your roaming profile. %appdata%\browserchoser2 Either it cannot create that folder or something is blocking the embeded DLLs from being extracted.

I am also assuming the app when into safe mode, which lets the main screen show. As to why the options wont work, not sure.

I found the options XML in the location you said %appdata%\browserchoser2 I was able to edit and save the document. Now when I open browserchooser2, the settings appear with my edits and I no longer get the error message. When I make changes to options in browserchooser2 and save, they are saved and I get no error message. I am not sure exactly what changed the behavior of the program after these edits, but the issue is resolved and I cannot re-create it.
My only suggestion is to add some documentation on the website so users can easily locate the options file if needed. I tried looking through the source code and it was not obvious to me (but I am inexperienced with VB). Thanks for the response.
Let me know if you'd like me to try and re-create the error somehow, or if I can be of assistance in another way.

I know, documentation is my week point.
The code that chooses the save path is a little hidden because of portable mode.In the settings.vb file, if you look at the DoSave function you will see the logic. If you did a seach for %appdata% it would not find it because I used the native .NET functions: Environment.SpecialFolder.ApplicationData
If you can reproduce the error, that would greatly help. But don't waste too much time. I am glad that fixed your problem.
