I accidentally delete the IMDataAggregator directory on a fresh install and now when I try to install it again it assumes the default settings and does not allow me to pick a different install directory.
This is due to some components still lingering in the system as the Uninstaller was not run
Release : 3.7
If this is a fresh environment and no DC or PC systems have been created yet, the simplest option is to allow the installer to finish the install attempt and then run the newly generated Uninstaller. This will clear out any remaining artifacts and from there you can install once more and specify your requested install directory.
