Query: XP ruined the Microsoft products on my Dell computer

I installed this product on my Dell computer. It did not try to register itself, but I got the message that installation was complete. I cannot access Word, Excel or PowerPoint. I was not able to uninstall it completely. Windows 98 and Explorer are hardly working. I cannot access my Office 97 or even uninstall it and reinstall. Dell Computer is of absolutely no help.Office XP is dangerous garbage.
