Hi Peter That appears to do the trick, thanks. I can't add conditions to the custom actions but if I add this to my patch it doesn't apply any of the config modification steps:
<OptimizeCustomActions SkipDeferred="yes" /> So - it must be one of the deferred custom actions... I will need to do some further tests but its looking good! One final issue which would be ideal if I could resolve is that on uninstall of the patch it seems to apply the custom actions - is there any way you know of to suppress that?
