What does the "source is an admin image" mean?

Question

I read the WiX documentation here:

AdminImage (YesNoType) - Set to 'yes' if the source is an admin image.

I don't understand "the source is an admin image" phrase. What does it mean?

Answer 1

This attribute corresponds to Bit 2 of the word count summary property. You won't typically set this directly. Instead it gets set for the cached .msi file created as part of an administrative installation.
