Cannot open PowerPoint 2010 files with an error message

Hi TechyV buddies!
I have encountered an error message in opening a PowerPoint file.
I am using office 2010.
And I want to solve this error message. The message is this:
“C:Program Files (x86)MicrosoftOffice14ppcore.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 system administrator or the software vendor for support.”
Can anyone tell me any solution to this?
Thank you!
