Yeah. Basically, download the installer and run it from Windows 7. When it asks for the installation path, point to the current installation. The only thing you need to be careful of is drive letters. If you have a new partition for Win7 that has different drive letters than you have in WinXP (or whatever your other OS is), then GameEx will probably get confused where things are located. If that's the case, then you probably just want to copy the GameEx directory to another location and install there for Win7.
