I think I have a problem similar to what a lot of other folk here have, where I can't install the beta version of photoshop because it tells me that "A conflicting or pre-release version of Adobe Photoshop cs6 exists on this computer." I had cs6 before, but then uninstalled it. I guess it wasn't uninstalled completely because when I try to install the beta I keep getting tha terror message.
Please help! Thanks.
Please let us know what type of system you have (mac/pc, os...) and how you uninstalled. Also, did you get both copies from Adobe? If you did not get the beta from here, then it is not official.
