Deb C. Report post Posted August 10, 2013 Was wondering if you can have two versions of PSE and PRE installed on a MacBook Pro (Snow Leopard) at the same time. Does it slow down the laptop? If you can, how does it work? Do the pictures just show up in whatever version you open to use? Was thinking about having version 9 and 11 on same laptop, if possible. Thanks.

tiza126 Report post Posted August 10, 2013 I'm not sure about a Mac, but I have 2 version of PSE (5 and 9) installed on my PC desktop and laptop. I don't run the programs simultaneously. Not sure it really slows things down much, but it does take up a lot of program memory. I set PSE 9 to be the default program for PNG and PSD files, so 5 will only open when I tell it to.

SandiC. Report post Posted August 10, 2013 Sure you can. No problem. I've had more than one version of Photoshop (CS4 and CS5) with no problem. Share this post Link to post Share on other sites
