Error when opening Excel files

[hungryplet]

Good afternoon, dear friends! Now 3rd day fighting with the problem: when opening the file Excel gives the error "the File is corrupt and cannot be opened". Some of the file properties there is a button to "Unblock", after which they are open, but there are files that do not open are not having this button, and indeed want, to do was not open all files without any rash actions. The problem with the Office 2010.
