New Post: Microsoft Excel 97-2003 Worksheet (.xls) bad signature override?

First and mosr important:
This tool is superb. Most comprehansive and works perfect for me.

Still - I have a problem with my files:
I get from a third party Excel 97-2003 xls files with bad signature (or header). I checked the signature, and indeed, it is bad.
The starange thing is that MS Excel will open the files OK, while the ExcelBinaryReader will reject them as bad (Justifiedly).
I tried to find a way to override the signature checking, but it looks quite complex.
Can anyone help?

Here is the file:
