Installing two version of RMC 4 at same time?

[buggaboo]

I am wary of new updates of RMC4! I'd like to test them before committing to them. So, is it possible to install two version 4s at the same time? Say a 4.10 and a 4.19?

If so, how?

Not sure whether this will work or not, but have you tried to install different versions into different folders?
