Following on from a previous post about installing > 1 copy of Aurora being ackward ( http://www.intellij.net/forums/thread.jsp?nav=false&forum=22&thread=65202#763720 ),
I uninstalled my current version before installing the new one.
This (as expected) left the config and system folders under the installation folder (that where I'm choosing to put them at the moment).
However, when I tried to import these settings in the installation wizard, it wouldn't let me, because it said "Unable to detect location of IntelliJ IDEA settings".
If you're keeping your settings etc. under the installation folder, then the combination of this problem and the one about multiple Aurora installations makes it ackward when a new build of Aurora comes out.
