Windows File Associations Not Working

I am having is that my Windows files never seem to associate with any programs that I install.

For example, after I installed Acrobat on my Win XP machine, PDF files are still not associated with any application. Thus everytime I double-click an PDF file it asks me to select a program to open with.

How can I allow Windows to properly associate files?

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
