Command line with rollback atribute

We have a command line to execute autoamtic updates, this is our line(this line are in the xml file:

<Files dir="basedir"> <File source="E:\Clientes\_cl\RELEASES\_vr\O+RH.exe" execute="after" waitforexit="true" retrollback="false" />

We need to add "execute file after updating is complete" and "wait for execution.." options in out command line, but we don't know how it works because we add the options in the xml version file.

What's the question?

If i add the lines which are in the xml (first post) the options are not enabled, i need to know if that is the right way to configurate options rollback
