SCCM Error 0x80240009
SCCM Error 0x80240009 was thrown on an endpoint during monthly CU deployments. The issue occurs when the downloaded package contents are not downloaded completely or may be corrupted during the download. It may occur due to multiple reasons like:
- Network glitches or
- Your AV appliance is poking its fingers all over the pie, or
- Two or more windows updates are in progress at the same time.

In our case, we updated the AV appliance agent and it started behaving like a newly commissioned K-9. Putting its nose across every new package downloaded in the cache folder. Had to whitelist the paths again. For the affected machines where, post policies re-evaluation – the update was still pear shaped, use the following solution.
Solution:
- net stop ccmexec
- Goto %systemroot%\windows\software distribution
- Rename download folder
- Goto %systemroot%\windows\ccmcache\
- Rename the relevant folder containing the update file downloaded earlier
- net start ccmexec
- Rev the update policies one more time
