Recently deployed my web app on Windows Server2008, IIS7 (with Office installed). After chasing (& catching) various other errors, I'm facing one I'm not sure even where to begin.
On Cassini (visual studio dev server) everything worked flawlessly (reading excel through excel interop).
On w2008 IIS it throws vague error:
Value cannot be null. Parameter name: o [ArgumentNullException: Value cannot be null.....
Currently, I'm going to add null check and see if things get better but I do suspect that it just blows up and disposes on finally block before it even starts reading anything.
Tried to set application pool to run under localsystem, but that didn't change anything.
