[wix-users] Custom Action with elevated privilege

Fri Dec 14 07:53:52 PST 2018

First run is fine, but it shouldn't require elevation to configure the application. There are well defined locations where an application can store configs (either per user or per machine) which don't require elevation.

The issue with "but I just want to write this 1 file" is there is nothing preventing it from changing anything else.  And typically the installer developer and the app developer are different people, so while the 1 file may be true today it may not be tomorrow. Hence why if it has to be in a restricted location, it should be written/updated by a CA in the installer.

Handling config in an MSI can be a pain.  Running an EXE after the install can be a good compromise.  Usually when I do it  I make it optional and I have the make program call it on first run if configuration hasn't occurred.  I usually put the configuration data in a registry key or folder that doesn't require elevation.   This usually works well.

I typically only handle configuration in the installer when it's needed to execute sql scripts or setup a windows service or application with a certain account.  Otherwise I tend to push it to application first run.

Why not write a proper CA that can be ran during the installation sequence? What is its need for modifying machine state after the installation is complete?

I changed the manifest of the configuration executable. Now the event doesn't trigger the configuration executable's UI to show up at all. Any thoughts?

Manifest the executable to require elevation

Subject: [wix-users] Custom Action with elevated privilege

I'm creating an installer to launch an executable after the installation. The executable will only be launched when a checkbox is selected on the ExitDialog. I hooked up the CustomAction to the Finish button of the ExitDialog box. I'm able to launch the executable. But the executable doesn't have the elevated privilege. It failed to save the output file to the installation folder due to lack of privilege. Is there any way that I can accomplish this?

<Property Id="WIXUI_EXITDIALOGOPTIONALCHECKBOXTEXT" Value="Run Wizard to configure the Connector config file" />

<Publish Dialog="ExitDialog" Control="Finish" Event="DoAction" Value="LaunchFile" Order="999">(NOT Installed) AND (WIXUI_EXITDIALOGOPTIONALCHECKBOX = 1)</Publish>

<CustomAction Id='LaunchFile' Directory='APPLICATIONFOLDER' ExeCommand='[APPLICATIONFOLDER]Config.exe' Impersonate='no' Return="asyncNoWait" />
