I just installed the new wallet twice because when I installed it from the GUI, it looked like nothing happened (except for my fan spinning up for a while). It did everything right, except when it was done, it didn't tell me it had successfully completed and had added an entry to my launcher menu.
You need to add a message at the end telling me it succeeded and what to do next.
The installation process worked fine, but silently. It just needs a notification of success at the end so GUI users can see that it worked. The second time I ran it, I did so from a terminal where I was able to see what it did.
