Receiving Configuration Error, I've Never Seen Before

[Rob G]

Hi,

I am new to this ASP.NET thing and while going very slow, I am learning.
Then I got a Configuration Error out of nowhere when I ran my project.

I do have Excel as reference (but I haven't been able to use it yet).

My project has been running just fine and I am sure I did something strange
to make this occur, but I have no idea what I did. So now, all the work I've
put into this, is gone. Well, I hope not.

Any idea what could have happened and how I can fix it?

Thanks so much.

Here's the error:
Configuration Error

It sounds like the error is resulting from not having the Excel Interop
Assemblies
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnoxpta/html/odc_oxppias.asp

I believe that article will be useful. Namely the "Installing the Office XP
PIA" which are properly named "PIA"


Hope this helps

Thanks for the info.

I was able to remove the reference and it seems to be working OK right now.

I will still walk through the article you sent as I am sure to learn
something new.

Thanks again.
