You pretty much guessed it.  WiX is calling MSI Validation and those messages are a known behavior of Windows Installer when it performs validation.   You can make the messages go away by  disabling validation but that's not a good choice IMHO.  Validation is there to help you.

Hi everyone, my first post here.

We've been using Wix for a long time to make Windows Installers.  Thanks to all who have
contributed to this toolset!

My question is this:  Every time we build an installer as part of a Visual Studio solution, we
get a couple of events logged in the Windows Application event log:

Product: AstroFlat Pro -- Installation completed successfully.

Windows Installer installed the product. Product Name: AstroFlat Pro. Product Version:
Product Language: 1033. Manufacturer: ProDigital Software. Installation success or error status:

We don't actually invoke an install operation on purpose, and by all observations these events
appear to occur at about the time Light.exe is running.

Are these events always expected?  Is it part of an installer "test" of some sort?  If not, can
these events be suppressed?

Thanks in advance.
