Not able to open office documents from SharePoint

Let me describe the problem in details-

-I can open the documents from my desktop

-I can save the documents to desktop by means of SharePoint site

-But if i tried opening documents from the SharePoint site directly then I can’t open it and getting filename error message box.

-Tried opening the document in Mozilla Firefox and it works fine.

-Tried opening the document in Google chrome and it works fine.

-Now it’s clear that the problem is with the IE only. Let me tell you that I am not using 64-bit IE but using 32-bit version only!

-Tried clearing the cache and cookies in IE but same problem.

-Tried adding the site in trusted zone but same problem.

-Checked with other office documents like MS Excel, PowerPoint but same    problem.

Finally I have applied the following resolution:

1)   Run one of the Office 2010 application

2)   Click on File menu, and select Options.

3)   In the “Options” dialog, select Trust Center in the left pane.

4)   Click on Trust Center Settings in the right pane.

5)   Select Protected View in the left pane of “Trust Center” dialog.

6)   Disable any of all of the protected view options as below by uncheck the check boxes:

·         Enable Protected View for files that fail validation

·         Enable Protected View for files originating from the Internet

·         Enable Protected View for files located in potentially unsafe locations

·         Enable Protected View for Outlook attachments
