World Documents won't open

Hello:
For some reason when I try opening world documents I will get this message:
"Works was unable to open the project you selected. The File May be corrupted.”
After that Microsoft Works will open and nothing will happen. This is using Vista.

I use to open most files using my old computer with XP but, but now with Vista I can't and the only way is saving then to the computer, opening Word and looking for the file and opening the file.
I am not sure if the installation of PowerPoint, Exel and Word for XP using Vista is causing the problem.(I install this from Office XP professional)
Thanks for your help
Luis

 

Question, do you have both Microsoft Office installed and Microsoft Works installed?

 

Yes I have both programs install now after trying a few time with Microsoft Works. I though installing Word will help.
