After installing MS15-115 older updates begin trying to reinstall. For example on one Windows 7 SP1 system the following updates show as needing to install:
MS14-068
MS14-074
MS15-055
MS15-085
MS15-090
MS15-122
MSWU-1329
MSWU-1485
MSWU-1526
All older updates show in Add/Remove Programs as being installed.
Error Message: 2359302 or 0
2359302 is a Microsoft code that signifies the patch has already been installed.
MS15-115 was installed out of order. Microsoft requires MS15-122, and MS15-121 to be installed before MS15-115 Please see TECH233504 for more details.
The defective targeting rules that allowed the problem to occur have been fixed by PMImport v7.1.741 (released on 11/13/2015) and PMImport v7.0.1443.1 (released on 12/10/15). This appears to be an issue for customers who rolled out the updates prior to the latest Microsoft revision 8.0 for MS15-115 dated November 13, 2015.
If the updates were installed prior to the fix then uninstalling the updates from MS15-115, MS15-122 and MS15-121 and letting them reinstall in the correct order resolves the issue.
