My old version of Photoshop Elements wouldn't work on my new computer, so I currently have the trial for PSE 21 downloaded on my computer, which I will be buying. However, I'm not looking at Premiere Elements with the video editing (something I've never tried). My question is if I download the trial of Premiere Elements 21 will it overwrite the PS Elements 21 I have on my computer? I already spent a ton of time installing fonts, syles, etc and don't want to have to redo everything so I was hoping the video editing program could be downloaded seperately. Thanks!
The two programs are entirely independent (although both come with the Organizer). If you have already installed Photoshop Elements, when you download and install Premiere Elements, the installer will check to see that you already have the Elements Organizer installed and will not install it again.
Premiere has its own set of preferences and changing them will not affect the preferences you have made in Photoshop.
