Automatic uninstallation after failure of installation.

[Dirk Räder]

Hi,

my installer currently fails during some custom actions that execute
after most of the installation is done:
  <Custom Action="MakeIniFile" After="InstallFinalize" >
    <![CDATA[(NOT Installed) OR PREVIOUSVERSIONSINSTALLED OR
(Installed AND NOT RESUME AND NOT REMOVE )]]>
  </Custom>
  <Custom Action="RegisterAssemblies" After="InstallFinalize" >
    <![CDATA[(NOT Installed) OR PREVIOUSVERSIONSINSTALLED OR
(Installed AND NOT RESUME AND NOT REMOVE )]]>
  </Custom>
  <Custom Action="InstallComApplications" After="InstallFinalize" >
    <![CDATA[(NOT Installed) OR PREVIOUSVERSIONSINSTALLED OR
(Installed AND NOT RESUME AND NOT REMOVE )]]>
  </Custom>


When one of those custom action fails, an error message is shown to
the user - but a rollback is not initiated.

How can I make WiX / MSI initiate the uninstallation?

Thanks in advance,

Dirk Raeder

Rollback doesnt get run for errors occurring after InstallFinalize. You need to schedule your custom action earlier.

This older post might help to explain.

Hi Peter,

thanks for the explanation. Unfortunately, I need to access the
installed files during the custom actions - as far as I have found
out, this is not possible during the transaction.

So, is there any way to schedule an uninstallation? Maybe even via
setting a mark in a defined file, scheduling a reboot and then look
for that mark?

Thanks,

Dirk Räder
