I see of many of you who have windows 7 being unable to install anyswitch, and its because you are usually saving it to the wrong place. This is because you're file directory is programe files (x86) where as vista and before, which is what the installshield is programe files
So when you see this screen setting up anyswitch

you must change this

to this

thats "Programe Files (x86)" that you need for windows 7.
So you should have this file extention
C:\Program Files (x86)\EA GAMES\Battlefield 1942\Mods\bf1942\Archives\bf1942\levels
Ive noticed a few users stuggling with installing anyswitch on windows 7 and for this reason
i hope this clears up any confusion for you guys
