IE7 Install which doesn't over-write IE6

[furnace]

I need to keep IE6 so I can compatibility-check sites.

I've got an old standalone version of IE7 installed - I have no idea which version it is, but they cleverly programmed it to block drop-down form fields as popups.

I got a mate to go to the same site in IE7, and it didn't block the drop-down, so I must have some wierd and wonderful version of IE7.

Does anyone know where/how I can get the latest version of IE7, but as a standalone (e.g. one that doesn't get rid of IE6!) ?

cheers

S'alright - I'll install IE7 then re-install IE6 using Multiple IE Sorted
