Updates KB2478662 & KB2446710 fail with error code 80070BC9
Systeem is Windows 7 HP SP1 64-bit.
Since 25-1 updates KB2478662 and KB2446710 (security supdates for .NET Framework 3.5.1 on Windows 7 Service Pack 1) fail with error code 80070BC9.
All other updates including .Net 4 install normally.
I have tried:
- clean boot
- updates one by one
- fixit
- system update readiness tool (kb947821)
- sfc scannow
I would like to de-install .Net 3.5.1 but this feature does not seem available in this Home Premium system.
Please advise (other than system reinstall)
