Have you followed these instructions from the download page? -

extract the vvvv directory from the .zip archive to a nice place on your harddisk.
run crack.exe
if you see red items, follow the instructions
if you see 3 green lights -> exit
run start_with_demo.bat
or vvvv.exe for a plain patch
if you encounter any problems during installation see troubleshooting
