installing problems

im having trouble installing the emulators and the games. when downloading i save as zip and all files (due to windows vista it wont let me save as any others). when i find the file where it saved...its always saved to open up with adobe reader which wont work....how do i change it to the proper program to open with...and what is the proper program to open with?

Opens with "WinZip", a free achiever and compressor. Right click on the file and select "Open With" and should bring up a list of programs, if installed, scroll down to WinZip and mark "Always use this program to open these files" and click okay. Should work, though seems the problem may be because you don't have WinZip installed or another program is associating with it and not allowing WinZip to open them. Hope this help ya.
