How to play vanilla BG2:EE with BG:EET installed?

Hi, all!
So, just how can I do it?
I can still play vanilla BG1:EE and SoD OK, because it has separate shortcut, but not BG2:EE.
Its shortcut leads to BG:EET and its .exe does it either.
Please, help.

P.S. I know, that I can play all BG campaigns from BG:EET, I need access to vanilla BG2:EE due to save incompatibility.
