I have installed Adobe Reader X, Air and Acrobat but since then the pdfs no longer open automatically and I dont know how to get the to do so. While trying to fix it, I mistakenly confirmed an "open with" for jpgs also with Adobe. And now I cant open any of my jpgs because a notice comes on Adobe saying that the coding is wrogn. Wha a mess! Can anyone help me with where to go and what to do. It just doesnt look as if there is any way to reverse these simple mistakes
Shift-right click a JPG file and select Open with and then Choose program.
Select the program you want to use for these files and tick the box that says "Always use the selected program to open this kind of file".
To associate PDF files with Reader do the same with a PDF.
