For files that have been modified after an MSI installation, if these files are in an update package (MSP) as far as I know there are 2 options available during the MSP installation: REINSTALLMODE=omus : Don't update files modified after installation REINSTALLMODE=amus: Overwrite files modified after installation.
We are dealing with installation of software components that have configuration files that WILL be modified after installation. If these files are updated in the MSP package, we need to support the following options: 1. If it is possible to auto merge the changes between the updated file and the installed file then perform the merge. 2. If there are conflicts that need manual intervention, then save the updated file as a new file (with a different extension for e.g. foo.ini.new) Is there any built in facility in MSP to support these requirements, specially #2, this is supported by RPM on Linux. I could not find any information that this is supported by MSP, so assuming the answer is no, the approach I was thinking of was execute a custom action after MSP installation either invoked from within the MSP or by the driver that executes the MSP installation. This custom action would interrogate the MSP for the files it contains and check if any of the files is a "config" file that needs to be either auto-merged or saved as a new file for manual merge. Examining an MSP package in Orca only shows MsiPatchMetaData table and MsiPatchSequence. There is no InstallExecuteSequence table for adding custom actions or File table to get the list of files in the package. At a minimum I would need to know the files within the MSP package. Is there a way to get the list of file in the package ? If so, please advise on how to get this information.
