Im trying to get DNN installed, and its giving me the following error, I searched all the forums and it looks like this is a unique error, because i cant find another thread with it. This error was given after fixing the common upgrade error that needs the DotNetNuke_template.mdf file. I put this file in the proper folder then got this error while debug='true'.

Server Error in '/' Application.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

For some reason, PortalSettings.GetProviderPath() is being set or not set and is NULL.
I looked through PortalSettings.vb in the source code and DataProvider.Instance().GetProviderPath() is the value that sets PortalSettings.GetProviderPath().
However I cant seem to find where DataProvider.Instance().GetProviderPath() is being set in any of the code.

Why wont the varible set itself?

I set PortalSettings.GetProviderPath() manually to "TEST" and then I get an error code without a source code, stack trace, file name or anything.
Says "Error Installing DotNetNuke
Current Assembly Version: 04.00.02
The type initializer for 'DotNetNuke.Data.DataProvider' threw an exception."

I dont know if this has to do with the previous portalsettings error or not.
What should PortalSettings.GetProviderPath() return?

Hello, My Name is Eka Siswanto. Using Reflector.Exe without viewing actual source code, it is obvious that the method you are seeking is indeed an abstract class and it is actually implemented in DotNetNuke.SqlDataProvider.dll.

Given that information, you can consult the actual source code to find the implementation of GetProviderPath method.

If you can compile and run your compiled version, you can use Debugger, or just arcane "Response.Write" method in the section of method to find the actual problem. Well, although it is so much to be said, the last word is just... Happy Trying, OK ?

Brgds,

Eka Siswanto
