Thanks Eric,

I’ve followed your suggestion and have tried both versions 2.5 and 2.6 and they both give the same error. Sadly, we have switched to the NPOI library which works with the file created with ZLIB, although more slowly. The strange thing is that Excel handles the file fine, and I would have through it would have used something like System.IO.Compression. Thanks for your help, that was useful.

Thanks again,
David.
