Why are you trying to open MS Word through the Windows Explorer? Do you also get this message when opening MS Word through Start? And have you tried opening MS Word by double clicking a MS Word file?
Do you have a regular installation or are you using a Click-To-Run installation? In the former situation I'd recommend a fresh installation of MS Office. In the latter case I'd recommend a repair of the Click-To-Run installation.
I removed and reinstalled office but I did not get any results.
When I click run on the adminstrator options.
What is the purpose of MS Word?
I can not open any file from the Microsoft Office suite Like word,excel and powerpoint.
Then it should work if you uninstall Office and reinstall via the media you bought in on. If it doesn't work after a complete reinstallation of the Office pack you should contact the supplier where you've bought it.
Are you really sure you've got a LEGAL Office version? Not some downloaded crap with a patch or something like that?
