Microsoft Office Excel cannot access the file

You might have experienced a problem while opening an excel file using



Excel.Workbook workBook = app.Workbooks.Open(Path, 0, true, 5, “”, “”, true, Excel.XlPlatform.xlWindows, “t”, false, false, 0, true, 1, 0);


and ended up with the following error


Microsoft Office Excel cannot access the file ‘\ExcelFile.xls’. There are several possible reasons:


• The file name or path does not exist.

• The file is being used by another program.

• The workbook you are trying to save has the same name as a currently open workbook.


This problem occurs on IIS 5 and IE 6.


It is a known issue and Microsoft offers a hotfix for IE 6 to overcome this issue.
