How do I change my default adobe program, so the items open Adobe reader and not Adobe Photoshop?

I know how to change the defaults so that items that are saved on my computer open in Adobe Reader vs Photoshop. I also know how to right click and openwith reader over an another adobe program. However, when trying to open some items in links/hyperlinks that are PDFs, my computer still opens them in photoshop. The default setting on my computer for PDFs, listed in the folder options, is set to open in Adobe Reader.How do I change my default adobe program, so the items open Adobe reader and not Adobe Photoshop?
Right click on the PDF and choose Open With. Select Adobe Reader and check the box to always use this application, then press ok.
