i run with two different profiles, one for 3.6.11pre and one for 4.0b7pre.
the startup line in the desktop links have -p "64bit" appended for the x64 profile, the x86 one has -p "wayne" appended for my original x86 profile.
a couple of addons that i use in x86 do not work properly in x64 due to differences in tabs handling. use the x86 with -p appended to the command line to bring up the profile manager, you can then create a new profile, and i copy the old one to the new using FEBE addon (which does not yet work on my system in 4.0b7, there is a beta febe for 4, but won't work on mine)
screen dumps of the link properties attached. each runs the proper .exe and without the addon check every time you switch.
