Adobe Acrobat Reader File Associations

I’m using Win98SE. I have Acrobat Reader 4 installed and recently installed a copy of the entire Acrobat Package (Reader and Distiller), version 2.1. Subsequently, I’ve got two copies of the reader installed and every time I try to open a PDF, it opens in version 2 of the Reader, not version 4.

In Win98, how do I force the OS to associate .pdf’s with a certain application?

Use explorer, find the PDF, right click on it, select OPEN WITH, then find the version of Adobe Reader you want to open it with. It should use that in the future.
