I have a excel file I've put on a file server. When required i access it via a dll, fill it with some data in background only (through ExecuteExcel functionality).
It used to work before. Recently I changed 2003 office to 2010 office version. After that it started throwing below error.
System.Runtime.InteropServices.COMException (0x80070BBC): Office has detected a problem with this file. To help protect your computer this file cannot be opened.
Even now also it works sometimes, and sometime throws above error.
What is the problem here?
