Wix Burn exepackage property

Question

I am trying to setup a property to be used within the "InstallCommand" field of "Exepackage", the property is a registry key value which will then be used within the install command to determine the installation location.

I have found the below links with concern of something similar for a msipackage however I am unable to get something similar working for an exepackage?

Can anyone advise please if this is possible?

WiX: how to access / change installation directory in managed bootstrapper?

Specify the INSTALLLOCATION of packages in WiX inside the Burn managed bootstrapper

Answer 1

You are on the right path. The install location will need to be passed in using InstallCommand. Your ExePackage needs to have a command-line option for setting the location.

If your package would be installed from the command line like this

setup.exe /install /quiet /InstallLocation=c:\somepath

your WiX should look like

<ExePackage SourceFile="setup.exe"
            InstallCommand="/install /quiet /InstallLocation=[INSTALLLOCATION]"/>

Make sure your Burn Variable is being set in the bundle log.
