I get an error message when attempting to open a generated XML Excel file.
The message says that there is an error log - but I cannot locate it the file
in the location quoted in the message. I have tried the same file on both a
Windows box and a Mac and can't locate the file.

Can someone please tell me where the file is. I have checked in case it is
hidden etc. but still no sign. On the Mac for some reason it says it is
placed in a normally hidden directory - but even knowing that I can't find it.

Any hints?
