I understand, I was trying not to repeat what had already been covered in the thread. My "/Any more info on this?/" was referring to Blair's previous comment: "/I'm going to seek confirmation, but this appears to be due to a known bug that can't easily be fixed that doesn't affect Vista and newer platforms./"
I have studied the logs in depth and the point of difference between the same upgrade on Windows XP compared to Windows 7 is: - On Windows XP, when uninstalling (quiet) the old bundle, instead of detecting dependents it states "... Plan begin, 6 packages, action: Uninstall Plan skipped removal of provider key: {9eae7624-4645-42ed-acf8-1b31e1a77abf} because it is registered to a different bundle: (null) ..." - On Windows 7, at the same point, burn correctly detects dependents, stating "... Plan begin, 6 packages, action: Uninstall Will not uninstall package: PackageD, found dependents: 1 Found dependent: {a24fa070-087f-4d77-a95a-b1c33abc707e}, name: My Bundle ..." Please find full logs attached. I greatly appreciate any assistance.
