I followed the instructions but now I can't launch because I have uninstalled the program. Is there a link that will allow me to re-install my licensed version of PSE15. I have the serial # and the order # of my purchase. Also in the security or permissions tab I wasn't sure which group to check. The top one "owner" was highlighted but I checked "user". Like I said, not sure.
It will be necessary to contact Adobe directly. Click the following link and scroll down the page to Individual. Then click “Sign in to contact us” It should be possible to start an on-line chat with Adobe Support. Make it clear you are not looking for support for an older product but need a download link to install and activate.
