This policy settings allows you to manage the MaxExecution timeout. During sealing, some processes (like AV-FullScan, .NET optimization, P2PVS, ImagingWizard, etc) will be triggered, if the MaxExecutionTime is reached, the process will ended.
If you enable this policy setting, you can configure the MaxExecution timeout from 30-120 minutes, default (60)
If you disable this policy setting, the MaxExecution timeout is set to unlimited
If you do not configure this policy setting, the MaxExecution timeout is set to 60
NOTE: If you configure the MaxExecution time to a low value, and the timeout is reached during P2PVS or ImagingWizard execution, the build process will fail.
