Hello all, At present when I go to Add\Remove Programs and click the Change
button, my installer launches and runs as if a new installation is
happening. This is ok as the features box does show what is installed and
what is not correctly, but one major drawback is that the user has to
re-enter where they want to install the files even if they are removing a
feature. So, a few questions:
1) How can I specify a different UI for the Change process?
The WixUI library provides a custom wizard sequence for maintenance mode.
2) When I run that process, is there a way to tell where the files have been
installed previously?
MSI remembers where components got installed but if you need properties,
you need to write them during install and read them during maintenance
mode. If you use the registry, you can use RegistrySearch to load them.
