installed sp1 on a test comp and (obviously i'll wait for the RTM for my baby) and i found that the Add/remove programs comes up with an error when you click on it..something about appswiz and or run.dll...needless to say i reverted back to the Luna theme (original) and still does not work..ps also unistalled style xp maually and with regcleaner...can anyone help?

Had the same problem, and I went to the SP1 uninstall folder in windows to uninstall

SP1. After the uninstall everything returned to normal. I also put SP1 on one new install of XP Corporate and it installed perfectly on a new bare installation
