If anyone ever asks you if you can build an installer at the same time the update service is downloading files, the correct answer is "No". You get this error:
CDK_Build_Invoke.vi.ProxyCaller >> CDK_Build_Invoke.vi >> CDK_Engine_Main.vi >> IB_MSI.lvclass:Build.vi >> IB_MSI.lvclass:Engine_BuildDevPart.vi >> NI_MDF.lvlib:MDFBuildDevPart_Open.vi
The following errors and warnings were recorded during the build:
Error: Program conflict.
Details: The deployment cannot be built because another installation/uninstallation session, deployment session, or NI Update Service is running. Finish that session and try again.
Code: -30
Error: Functions were called in an incorrect order.
Code: -31
