Again, find a .pdf file, RIGHT click on it, choose "Open with", then select "Choose Program".. Once there, place a CHECK mark in the box next to "Always use the selected program to open this type of file". This time, if Adobe Reader isn't listed is the list of programs, then click on the "Browse" button and navigate to C:\Program Files\Adobe\Reader 10.0\Reader, then double click on the "AcroRd32.exe" file listed there.. .It should open your PDF file and keep the associated program correct.
Hope this helps.

I recently downloaded a PDF file & from Download Manager, double-clicked to open the file, as I normally do. I got the small window that prompts for which program to use to "Open File With." There was no entry on the list for Adobe Reader, but there's a button to Browse & Add programs to the list. But once I located the program, there was no way to get the program added to the list! Clicking on the program only opened its files. I tried typing in the name Adobe Reader & that didn't work either. Then I made a Big Mistake. Not seeing that a program on the list was highlighted (gray) I clicked "Always Open File With This Program" thinking it would be the one I typed. OOOPS! The program is for image-editing, and is now 'permanently' the program selected to open PDF's - which of course doesn't work. I looked in Help, which said there's a place to click "Change" but I didn't find that button anywhere! And Now I'm Stuck!! I'm still a 'dummie' so I need some step-by-step help to 1) undo the wrong program for "Open File With" & 2) How to get Adobe Reader onto the list. (other option given is to go to the web to find the desired program - doing that doesn't work at all). HELP! please... I use PDF's often enough to need to fix this asap, I can't open any existing PDF's, and the same procedure of adding programs to The List might be needed in other situations. Thanks in advance!
