Running Poser 5 on Win XP, with Win 2000 simulation, as it crashed repeatedly on the registration process on Win XP. This works. However, I can't get the updater to install. CL tech support advised reinstalling the minimal version over the original full installation of P5.Did this and it still won't install. If one completely uninstalls P5 and does a fresh install will you then have to go through the registration process again? Would this solve the problem of the SR1 patch not installing?
