You can't use instance management to perform an upgrade install. When you select an existing installation it really runs the old install in maintenance mode and not your new install at all.
So to use it you really need to select to install a new instance and the user would have to know to select the same install folder.
To get the old values from the previous install, you can read the properties files in the old installs uninstall folder. IA has a custom code utility to read in property files. I modified it to read in only the values I'm interested in instead of excluding what I don't want.
I am getting the same issue.
"An error occured while trying to manage the selected instance."
We are using IAW 2011 SP3.
Please do the needful ASAP.
Please let me know where will this Uninstaller action will be??
