I use some config files in my application (e.g., web.config) that can be modified by the user after the installation. Are there any support by InstallShield, to preserve the changes made by the user when an update of the application is installed? I just can overwrite the config files with the new ones from the update installer - but then I will loose the changes. Can IS handle those cases?
The only way I've been able to deal with this in the past is to interrogate the XML files for the relevant info, overwrite the original xml files with the new ones from the upgrade, then modify the default values with the info previously obtained.
During the original install you could save any relevant info to the registry, making obtaining it a tad easier.
