Question

I need to run executable for custom setup/tear down, after install and before uninstall. It needs to run with elevated privileges. How to do this correctly?

Answer 1

So, the final solution was like this:

<CustomAction Id="Install" Directory="APPLICATIONROOTDIRECTORY"
              Execute="deferred" Impersonate="no" Return="ignore"
              ExeCommand="[APPLICATIONROOTDIRECTORY]MyExeName.exe -install" />

<CustomAction Id="Uninstall" Directory="APPLICATIONROOTDIRECTORY"
              Execute="deferred" Impersonate="no" Return="ignore"
              ExeCommand="[APPLICATIONROOTDIRECTORY]MyExeName.exe -uninstall" />

<InstallExecuteSequence>

  <Custom Action='Install' After='InstallFiles' >
    $ProductComponent = 3
  </Custom>

  <Custom Action='Uninstall' After='InstallInitialize' >
    ?ProductComponent = 3
  </Custom>

</InstallExecuteSequence>

Any advise to improve it?
