[wix-users] How does bundle rollback work?

[Wesley Manning]

He's not using a rollback boundary from what I understand.  He's asking how rollback actually works.  It is not working the way he expects it to work.  If you don't have a rollback element in the wix burn will rollback everything except packages marked permanent I understand.

Yes, Rollback occurs in case of error or user cancel installation during the process. Technically, RollBackBoundary tells bundle to which boundary it should rollback. So it depends upon you how you want it to rollback.

For a package to stay permanent, define attribute Permanent='yes' , which is 'no' by default. I'm not sure, if a permanent package would be rolled-back in this case...
