Recently my videos which relied on Adobe Flash stopped working. I assumed it was because of outdated OS in my MAC, which I upgraded to Lion version (still old I know). I try to install Adobe Flash player, but after download I then am directed to a screen offering me other products for purchase (Photoshop, etc), but no ability to continue the install process. I have tried multiple times. Is my OS too outdated or is there some other problem that can be easily fixed? Is there something built into the OS that blocks installation? HELP! Any assistance appreciated.
