I'm using SCCM to deploy updates/patches for QuickTime. In some cases, I now have machines that show multiple versions of Quicktime in add/remove programs, such as 7.6.2 AND 7.6.9 both simultaneously. attempts to remove 7.6.2 on these machines fail, code 1605 (basically the wrong version). How can I kill older versions while installing current version? Or some other solution?
