The downloader needs to know where to place the downloaded file. That can be the desktop or the download folder or some other place you want. If you are given the option of running or saving the file, i'd recommend saving it. Then, after you know the file download completely, run it from where you saved it.
As for the applications themselves, on Windows 7 64-bit, 32-bit programs go into the "Program Files(x86)" folder and 64-bit programs go into the "Program Files" folder. The installer should provide a default installation location on the C drive that is correct for the version of the application you are installing. You shouldn't have to change unless you have some reason for installing it somewhere other than the default. It's generally a good idea to install in the default location.
Photoshop Elements 10 is a 32-bit application and will end up in "Program Files(x86)". Premiere Elements 10 has a 32-bit version and a 64-bit version. The 64-bit version will end up in "Program Files". I haven't installed Premiere Elements 10, so I don't know whether the installer will offer you the choice of the 32-bit or 64-bit version.
