First, download the VICE archive from http://vice-emu.sourceforge.net/ . Direct link to the archive is:
http://sourceforge.net/projects/vice-emu/files/releases/binaries/windows/WinVICE-3.0-x64.7z/download (you probably want this one on a recent hardware).
Open it from your browser (it is a 7ZIP archive). If you don't have the unpacker, you will need to install yet another program 7ZIP. It is a file manager/archiver. Extract the WinVICE-3.0-x64 directory to the system directory of choice (c:\Program Files is OK, but you can drop it to desktop).
Enter that directory and start X64.exe binary. Familiar picture appears. If you don't fancy "interlaced screen" look, you can turn it off in Settings-> Video Settings ->VICII renderer-> Render filter.
Joystick: Settings -> Joystick settings. Select Joystick #2 and select "Numpad + RCtrl". Later, you will want to remap this, but for now it will do.
You can start downloading games from my page (or elsewhere). You need T64 (tape image) or D64 (disk image) file. The simplest way is from menu: File -> Autostart Disk/tape image , click on Attach, and if the image is good, you will be sent to the game. After that, you must only pass the initial trainers/demos and start the game.
