That error that you posted is generally the error that you get when you're not using impersonation in your web.config.

Do you have any idea what the error was when you tried to uninstall the provider? What error do you get now when you try to install it?

I'll have to go through the provider scripts to see exactly where records are stored in the database and get back to you on where to look to verify that it's totally removed from your install. I'm not near an install that I can easily look at (I'm working in one of our labs today setting up for students next week) but it'll probably be late this evening before I can post it.

If you can give me more detail on the error you're getting when you install (or what you saw when you tried to uninstall) we might be able to get around it.

Saran...do you still have the impersonation line in your web.config uncommented? Maybe try commenting it out again and then trying to install. I'm thinking it may be a file permissions issue.

Hi Mike,

I even upgraded my dotnetnuke to latest version and try installing the new provider but still getting the same error.

Here is the full error i 've got.

As you can notice in the above error message, it fails when it tries to create a backup of previous version of web.config. You able to get anything from this?

Thanks,

Saran
