When I open any office file or application it displays the following message:
C:\Program Files (x86)\Common Files\Microsoft Shared\office14\mso.dll is either not designed to run on windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.
None of the applications would open. Please Help.

Thank you for using Microsoft Office for IT Professionals Forums.
From your description, I would suggest to try the following methods:
1. Close all to the Office programs
2. Go to the location “C:\Program Files (x86)\Common Files\Microsoft Shared\office14”
3. Rename the file “MSO.DLL” as “MSO.DLL.OLD”
4. Start Office component such as Microsoft Excel, Windows Install notification popup and start installing Office 2010.
5. After complete installing, Excel will be opened.
- Click Start, then click Control Panel.
- Click Programs and Features.
- Click the Office 2010 program that you want to repair, then click Change.
- Click Repair, then click Continue. You might need to restart your computer after the repair is complete.
Please take your time to try the suggestions and let me know the results at your earliest convenience. If anything is unclear or if there is anything I can do for you, please feel free to let me know.

I had a similar error involving the file C:\Program Files\Microsoft Office\Office14\OART.DLL. I couldn't uninstall or repair the Office installation so I was really struggling with it! Following your instructions I just renamed it to OART.DLL.BROKEN and the Windows Installer progress bar came during the repair operation, which created a new copy of OART.DLL and now all Office applications open correctly, thank you!
However, in my head this raises a question - if a significant error like this can be prevented by simply rebuilding a file, is this not the kind of thing that could programmed in to the software in a kind of try/catch scenario to prevent headaches like these? Might be a useful feature to include in a future version.
