I just got a new computer since my other one is on the verge of going out. I have downloaded Adobe Lightroom perfectly fine, but for some reason it won't let me download my Photoshop CS4. I save it to the computer instead of opening it when the download pop up first pops up and once it's done downloading, I go into my Download file to open it so I can finish installing it and it tells me it cannot open. Can anyone help me? Am I downloading it wrong? I did try a different way and open it instead of save it, and I did that through the internet... but once the pop up for that pops up it won't let me go any further. It's so frustrating as I really need it to be installed onto my new computer so I can use it.
