Hi,
 
I search a good solution to upgrade an already installed .Net
application. In this .Net application we have standard xml-config files,
which has only settings with application scope. I have searched for many
forum entries and it seems that nobody has useful information about it.
The logic should be so:
- the installer or reinstaller only creates the file if it is not found
(could be done with the permanent and neveroverwrite attribute of the
component element)
- the uninstaller should ask you if the programm should be removed with
or without configuraiton (does not works with the permanent flag)
- the logic has to be in one wix installer project, that means you
create a msi package with integrated installation and upgrade logic
 
It should later also be possible to add some migration or upgrade code
to the wix installer for the xml config files.
 
Thanks,
 
Thomas Mathis
