The installer MSIs don't create the registry entries currently.
pgenlist(a).dll associated with the drivers try to create the
entries when (maybe first) IDtcToXaHelperSinglePipe::XARMCreate()
call fails. Invoking 64bit MSDTC related applications would resolve
the problem if possible.

Because msdtc process seems a 64bit application, 64bit pgxalib.dll
should be registered even when 32bit applications use MSDTC support.
The current way of registration isn't appropriate and 64bit installer
would have to register the entry beforehand.
