Questions about Updating without Uninstalling
Posted: Fri Jun 12, 2020 11:28 am
Hello,
In the past when creating update builds we've always uninstalled the entire product and re-installed the update. Now we would like to do an "in-place update" so that we only update the components that have changed.
We don't want to build patches as each "update" should also be a complete install if a previous version is not installed.
All the installs I've done so far have been with MSI. I was thinking of handling the prerequisite and maintenance steps my self to not remove the previous installation, and then allow the install to proceed.
Is this possible to do with InstallAware? Would NATIVE ENGINE work better?
Thanks
