I saw this error in smsts.log when installing applications during OSD. AppEnforce.log had no errors.
I then found this error in CITaskMgr.log:
A little more sleuthing in the CAS.log showed the problem:
The cache was not big enough to download all of the required content. You can change your ConfigMgr client install parameters to increase the cache size (SMSCACHESIZE=XXXXX) to resolve this. In my case, I didn't want all clients to have the larger cache size, so I only applied this to one group of systems. In the section where I'm installing these apps, I add a PowerShell script to increase the cache size:
$Cache = Get-WmiObject -Namespace 'ROOT\CCM\SoftMgmtAgent' -Class CacheConfig
$Cache.Size = '20480'
$Cache.Put()
Restart-Service -Name CcmExec
