I have had both running for some time without issue. One
thing though you need to be very careful about. If you double click
an XPJ file in Windows Explorer, it will open in RH6 and then you
cannot open the project again in RH5. Well you can but that's
another story and is not the best plan.
What you or your IT people need to do, is reassociate the XPJ
file with RH5. You do that in Windows Explorer and it takes
seconds. Then X5 projects will open in X5 and RH6 projects will try
to but be blocked, you then open RH6 and point to the project or
right click and use Open With. Both versions of RH will be there
and it will be obvious which one to use.
Be aware the trial only handles a limited number of topics.
If in doubt, use a separate machine.
