Any help is appreciated:

I'm developing a C#.Net app in VS2010 that interacts with Excel. The app works correctly on my local machine. Uploading to a remote Windows 2003 server however, breaks the app.

Originally, I received the following message

• Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005

After Googling the problem (which suggested a permissions problem) i tried this:

• Installing Excel 2007
• Going into Component Services on the remote server and following the instructions here: http://blog.crowe.co.nz/archive/2006/03/02/589.aspx

Now I get this message on the same operation:

• Exception from HRESULT: 0x800A03EC

Google searches seem to be suggesting that this is a version match error. However, both the local machine and the remote server use Excel 2007.

Any suggestions would be very welcome. Thanks in advance.
