Dear Larsa,
I have tried to load the Excel 97 (xls) open password protected file with the latest version of XSS but failed.
The file was created as follows:
- Open a blank workbook in MS Excel 2016 (64-bit) under Windows 10 64-bit
- Save the file as the Excel 97-2003 workbook with the Password to open 'test' in the General Options
- Tried to do with MS Excel 2013 (64 bit) but the result remains the same
- Save file with newer format (xlsx) then everything works fine.
Thank you in advance for your advice!
