Open Without Password Field Prompt - Office 2007
Environment: MS Excel 2007
Excel password-protected file without password prompt when startup, which made the file unable to open.
I suspect it caused by the file is saved from Office 2010.
Finally, I fixed it after install the patch via the link below:

It is Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint File Formats
