Select a topic, then click I STILL NEED HELP to start Premiere Elements Online chat
How are you being stopped from installing Photoshop Elements 12 and Premiere Elements 12 on your Mac computer? Please be specific.
Are you getting stopped by the "Shared Technologies" error or something else.
Contact with Adobe via its Adobe Chat is an option, but you need to be careful navigating your path to it otherwise you end up with "Ask the Community".
If you decide to explore Adobe Chat, please use the following link to
Downloading, Installing, and Setting Up.
Downloading and Setting Up
I will set the link for the page with the Chat panel to click on. If the page set does not hold, then you will have to navigate specifically to
Downloading, Installing, and Setting Up which gives the Chat panel option.
However, at the present moment, whether you use the link provided by John or the one that I have, you will end up with Ask The Community - No Adobe Chat panel to click on. Looks like Adobe Chat is down again. It has been undergoing updating which was supposed to be finished by now. Guess not.
Consequently, let us see if we can work here to get you some Premiere Elements answers for your Premiere Elements questions - maybe even provide a Photoshop Elements solution in the mix.
Looking forward to your follow up.
