Question

I have the following code in my wxs file

<Directory Id="TempFolder" Name="Temp">
    <Component Id="TempExes" Guid="DF92ED79-28AB-4E88-81F2-8B035D4B8A01" DiskId="1">
          <File Id="CACLS_EXE" Name="CACLS.EXE" Source="Binary\CALCS.EXE" />
    </Component>
</Directory>

Now when I call a Custom Action from the installer, how do I get the path to this exe? I tried

var pathToExe = session.GetTargetPath("TempFolder") + "CACLS.exe"

which doesn’t work.
Any ideas? Thanks.

Did you try:

<Directory Id="TEMPFOLDER" Name="Temp">
    <Component Id="TempExes" Guid="DF92ED79-28AB-4E88-81F2-8B035D4B8A01" DiskId="1">
      <File Id="CACLS_EXE" Name="CACLS.EXE" Source="Binary\CALCS.EXE" />
    </Component>
</Directory>

and

var pathToExe = session.GetTargetPath("TEMPFOLDER") + "CACLS.exe"

public properties are in all caps.

I haven’t used wix in a while but if i remember correctly, if your custom action is scheduled to run during the part of the installation where changes are made to the system you have to use a special property if you want to be able to access the information.
