I have A Windows XP computer and I am trying to download a free-trial of adobe Photoshop CS4 Extended from adobe.com. After I downloaded the two files (.7z and an exe file), it asks me to extract the files. I did that, and then when I tried to launch the program, it said that windows needs to know which program created this file before I was able to upload it. It gave me a list of programs such as Adobe reader as suggestions for opening the file but none of them worked. Can somebody please tell me what program I need to open these files for CS4?

-thanks
