A web application with VB.Net as front end fails to upload Excel file to server on Windows 7. The Uploads folder rights should be granted to the IIS applicationpool user. This problem does not occur in Windows Server 2003.
The error message given to me is as follows: Microsoft Excel cannot access the file 'C:\Inetpub\wwwroot\SW\Uploads\IMPORT_file_4_2012-03-02_13.18.29.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
