How do I correct problems with installing Adobe Air on iMac OS Maverick? I want to download Pdf Air files and I keep getting " I don't have permission "!

Check in the System Preferences Panel under Security and Privacy, at the top of the window you'll see a toolbar that has 4 buttons "General", "FileVault", "Firewall", "Privacy". Click on the "General" button, at the bottom of the page lower right hand corner if theres a little pad lock thats locked you need to have the admin passcode to unlock it, from there on the lower half of the Preferences box you'll see 4 lines. If the padlock is locked they'll be grayed out. "They say Allow apps downloaded from" 3 radio buttons with various descriptions of what is allowed to be downloaded to that Mac computer. Try that, if it doesnt work, let me know, maybe we'll both learn somthing.
