Installation details:
LRTL - current download version
System - Windows 7 64 bit
Java - Version 8, build 1.8.0_66-b18
Lightroom CC, 2015.3 Release

Application visible in LR plug-in manager, and can render images via plug-in from within LR.

However, every attempt to launch the application interface from the Windows start menu results in a very brief display of a splash screen, some shuffling of entries in the Processes tab of the Windows Task Manager, then nothing. Same result after multiple reboots of system, application, Java and Lightroom. All preferences inside Lightroom verified as correct.

Any suggestions how I can get this thing happening?

I assume, you have installed the 32bit version of java, instead of the 64 bit version. Please uninstall all java instances via "Remove Programs", then install the 64bit java from the like provided here: http://lrtimelapse.com/install

We have lift off! Thanks.
