C# Importing Excel files doesn't work anymore -


I have an application that imports sheets from Excel files and processes them. I started developing on Windows XP and all were working fine, but now I had to switch to Windows 7 Professional X86.

The problem that happened suddenly, is that when the application wants to open a Excel file, it throws it one exception.

I did not change anything in the code, I just switched to working on PC. It works randomly on my personal PC (Windows 7 Professional X64).

Any help is appreciated.

Thank you in advance

Did you check file / folder access?
