| It is possible, but it is not supported. I think the V5.0 installation
explicitly asks you to remove previous installation.
It does work, but there are several gotcha's:
1. they have to be installed in two separate directory trees
(obviously)
2. there is some overlap in registry keys that they use, so flaky
behaviour could occur when going from one use to another use
3. the environment paths need to point to just one or the other
and each version's directory paths need to be consistent with that
version
there may be other stuff as well, which is why having both is
unsupported

| rereading the release notes, installing both in separate directories is
not explicitly unsupported, so I take back my statement that it is
unsupported.
the registery trees also seem to the separate, although it is still
something to watch.
3 in the previous note is still a concern
