Rollback feature?

Hey,

I searched the documentation for support for rolling back files if you abort the install. Is there built in support for this in NSIS? If not, how have you guys approached this?

Thanks in advance!

create your own backup-routine...

backup all files (or whole folder) which are newer...

you can use the IO for that

place your IO page (asking for backup) before installing newer data.
