Solucion

Try the following steps:

1. Open Excel (power point and word) 201x.
2. Click on File > Options.

3. Select Trust Center > Trust center settings.

4. Select Protected view.
5. Uncheck all the options under Protected View > OK.

6. Restart Excel (power point, word) 201x and try to open Excel (power point, word) documents.

Symptoms

When an Excel, Word or PowerPoint document is downloaded via Google Chrome, Office 2010 refuses to open the file with the error message "The file is corrupt and cannot be opened."  Downloading with other browsers works without issue.

Cause

Office 2010 introduced a feature called Protected View, which prevents documents from being opened if they are determined to be from an unknown source. Unfortunately, this appears to designate files downloaded by Chrome as unknown.
