WiX - Find parent of .msi directory

I am using WiX to create a custom installer. I want to navigate one directory up from the .msi's directory in order to find the path of an executable file. After doing some research, I found that [OriginalDatabase] points to the .msi's location, but I don't know how to search up from that location instead of down. Here is my search code:

<Property Id="SHORTCUT">
    <DirectorySearch Path="..\[OriginalDatabase]" 
                     Depth="0" 
                     AssignToProperty="no" 
                     Id="MainSearch" >

        <FileSearch Name="Program.exe" Id="EXESearch" />
    </DirectorySearch>
</Property>

WiX will not let me add the "..\" in front of a preset directory path. I don't know how else to navigate up from that folder. Any suggestions would be greatly appreciated!

Solution

  • Windows Installer has no such ability. You'd have to write a custom action to resolve OriginalDatabase and then work up to the parent from there.
