Hi,

The Excel file is generated through ASP.NET C# Web application. But getting error while opening Excel file with Windows server 2008 R2 and at local Windows XP it is running fine.
Error is "System.Runtime.InteropServices.COMException (0x800A03EC): Exception from HRESULT: 0x800A03EC" we have set same culture settings at IIS server also and we have given permissions also. We are able to save Excel file there but not able to open it.

We are opening the file using the code below:

xlWorkBook = xlApp.Workbooks.Open(strExcelPath, 0, true, 5, "", "", false, Excel.XlPlatform.xlWindows, "",false, false, 0, true, false, false);

I request please help us with this issue.

Thanks
Mahesh..

System.Runtime.InteropServices.COMException: Exception from HRESULT: 0x800A03EC[^]

Possibly you need to set permissons. Here you go Click[^]
