Can't launch Lightroom trial

Just downloaded Lightroom for a 30 day trial. Am running Windows 8.1. Download & installation went fine. Tried to start application, it switches to desktop mode, Lightroom appears on the bar at the bottom of the screen but nothing on the desktop no matter what I do. If I hover the cursor over Lightroom it shows a window where I should click a box to enter a serial number or click "I want to try". As soon as I move my cursor to the window it disappears. Clearly it's impossible for me to launch the software so I can't evaluate it before buying

I'm not sure exactly what's going on, as LR should be visible if the quick-peek shows something, but I can think of a few obvious things to try:

0) Before trying any of these, make sure LR isn't already running, so if the taskbar icon is still there, right-click and choose Close window. Then right-click on the Task bar and look at the Processes and Details tabs and make sure that LR is not still running, somehow, and if it is right-click on the lightroom.exe process name and choose End Task. Give it 15 sec after it disappears before you forcibly removing it because it does have some cleanup tasks to do as it's shutting down.

1) Back on the Windows 8.1 start panel, find the LR icon, right-click on it, and choose Pin to Taskbar, then switch back over to the Desktop, and try starting it from the icon on the task bar, so a switch-to-desktop isn't happening immediately before the program tries to start up.

2) If you haven't already, reboot, and try it, again. As part of this, try running LR as administrator. To do this, right-click on the LR icon on the task-bar, right-click on Lightroom in the list of items that comes up, and then click Run as Administrator.

3) Try uninstalling and reinstalling LR5, in case something didn't quite work the first time.

4) It may be a video problem so run Windows Update (from Control Panel) and make sure you are up-to-date with everything, there. It' might also be wise to download and install the latest video driver from your video-card manufacturer that is compatible with Win 8.1.
