CS Mimesweeper and aspose.cells


a v3.5.3.0 produced Excel file is causing my CS mimesweeper to reject access to the file.

The sweeper is producing the error message: ...File contains a stream with an invalid starting sector.

Anyone with experience? or hints?


Could you post the file that caused this problem? Can you open it in MS Excel?


I've sent you the files by e-mal.

Also, I've upgraded to the latest version (, however, still, the aspose.cells generated files are blocked (Excel generated files are not).
