I've got myself Photoshop cs6, and I like its new features. However, I'm also making heavy use of Photoshop plugins, and many of those aren't yet compatible with the new Photoshop . I'd like to be able to start Photoshop CS5 and Photoshop CS6 at the same time. My PC certainly has the capacity to do that. However, once I start Photoshop CS5, I can't start Photoshop CS6, and vice verse.
I know that this is possible to do in principle, because I've configured my PC so multiple users can log in and work at the same time, and I've tried to start multiple instances of Photoshop via remote desktop, which worked
I've tried starting Photoshop with
runas /user:photoshop "C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)\Photoshop.exe"
to no avail. It still just gives focus to Photoshop CS5, which is already started.
I'm doing this on windows 7.
How do I trick Photoshop into starting 2 instances of itself at the same time on the same windows desktop?
