I suspect renaming the folder would not work because the install
registers the DCOM server.  Copying the libraries might be okay, if
you then did a regular install of a package to update all the indices,
but there might be some other detail I missed.

Probably the easiest thing to do is to install the new one on top of
the old rw2010dev, by changing the default install directory when you
run rw2010alpha.exe.

The safest thing is to install to a new folder and download all the
packages again, because then you won't have any files installed which
shouldn't be there.
