Possible to install multiple instances side-by-side?

[thoelze1]

I am trying to run two instances of the dext at the same time. My first idea was to install different versions side-by-side, but even different versions install files to the same locations and probably collide in other ways that I cannot see. Would it be possible for me to change elements of installation so that two instances can coexist on the same machine and run concurrently?
