I've generated a sample excel file with excellibrary on my Windows 7 machine, 
and when i try to open the generated with Excel 2010 i get an error that says : 
"Can't open file invalid file format"

because currently the support is for xls files prior to excel 2007 xlsx format.
we plan to support them in the future

ok,
but Excel 2010 correctly open up every legacy file format like xls, while it 
doesn't open only the xls file generated with excellibrary ...

I think that there's something wrong in the generated xls file by excel library.

This should not have been closed...I have the same issue - I can open every 
other old .XLS file except the ones generated by the dll.

2010 can open 97-2003 version .XLS files, so why do the ones generated by the 
dll fail to open?

To reiterate - this is not an XLSX problem....

The problem is that Office 2010 doesn't support it unless there are 100 or more 
Cells Filled.  

My work around was to have it fill 100 cells in a for loop with "".  That way 
it gets it's 100 cell count in and then it works just fine.  

VB.Net

Dim filename As String = "c:\MyNewFile.xls"
Dim workbook = New Workbook()
Dim FakeWS = New Worksheet("FakeWorkSheet")

workbook.worksheets.Add(FakeWS)

For i As Integer = 0 To 100
    FakeWS.Cells(i, 0) = New Cell("")
Next

workbook.save(filename)

Cheers^^
