The suggestion by Edward below sounds very good. Please let us know if it helps.
#1. An alternative method to #1. Drag and drop the line/icon from Start/Programs to your desktop (keep ctrl-key pressed: you'll see a plus indicating copy, not move; important detail!). Then rightclick on the icon on the deskop, choose Properties, and add /a at the end, so that it looks like
"C:\Program Files\Microsoft Office\Office\Winword.exe" /a, as mentioned in the Microsoft article. Click OK on the properties sheet, then run it like any desktop icon by clicking on it.
#2. Start Explorer, browse to the folder it's in in the left pane (you get the folder name from #1, it's something like C:\Program Files\Microsoft Office\Office\ .Then browse to winword.exe in the right pane and click on the program to run it.
These are rather elementary things in Windows. If you don't master them, you should read a book like 'windows for dummies' or follow some introductory course.
