Gringo,
you might want to replace Response.End() with Response.Flush.
Let me know if this works for you.

Daniel,
Sorry, it didn't work. I didn't get the error, but the HTML returned to the
Excel file. Putting the response.flush() after the response.close() or vice
versa still generated the error.

Yes, this is the way ASP.NET attempts to insure that the processing halts
for the current request -- they throw a ThreadAbortException. Sort of odd,
eh? Well, the magic with a ThreadAbortException is that if you put a try/catch
around it, it still gets thrown outside your catch -- they're doing this
so you don't catch their attempt to terminate the request. So, in short,
it's just how it works.

a Response.End() does a flush, then kills the current thread (to stop
continued processing). ignore the thread abort in your catch
