There is no such thing as an uninstallable version of DX.
They are what Microsoft calls core components of your OS. What one can do is
if you are running Windows XP or Windows ME is use the restore function to
return to an earlier time before you installed the newer version of DX.
Besides DX 9.0b is a patch that addresses problems that were in DX9.0 and
DX9.0a.
Hope it helps

Hi all,

Did any of you who got as far as starting the install of this notice the
warning
that it can't be uninstalled?


Does anyone know if it's a 'beta' version of some kind? If so, the
webpage
doesn't say so.

If it's not uninstallable, what happens if the PC is a disaster area after
the
upgrade? (Like mine was...)

Happy landings
