Sonar LE won't open.

Recently I was forced to accept the Windows 10 Fall Creators Edition version 1709. Previously, Sonar LE was running flawlessly with version 1703. I could uninstall the new version and go back to work,
but only if I left my computer powered on. This worked for a while. 
 
Whenever I turn my computer off however, I end up getting stuck in a loop that will not allow Windows to startup at all. If I boot from a flash drive sometimes it starts, sometimes not. The fix is IN the update.
 
So here I am without my software. I need it. My whole artistic process revolves around this tool for charting and transcribing.
 
I have tried a ton of fixes including reinstalling but I can't figure out what to do.
 
HERE'S WHAT HAPPENS, THE SONAR SPLASH COMES ON THE SCREEN THEN GOES AWAY, THE AUDIO DRIVER LOADS WITH A WINDOWS INSTALLER GRAPHIC, A SIMILAR GRAPHIC POPS UP THAT SAYS, 'PREPARING TO INSTALL' AND THEN NOTHING.
TASK MANAGER SHOWS NO ACTIVITY FOR THE SONARLE.EXE AND THE ONLY WAY TO STOP THE PROCESS IS TO END IT INSIDE TASK MANAGER.
 
I tried to install some other software, too and it does the same thing.
 
System:
 
AMD FX4300 Quad Core 3.8 GHz
16GB Ram
64 bit OS
 
 

thanks slartabartfast,
I was able to uninstall the 1709 update just fine. The problems is that windows won't let me keep the version 1703 going because its vulnerable. For Windows Home Edition, updates are mandatory, I can postpone only once. I could just keep the old version running 24/7 but then I can't get online because as soon as I do... it starts downloading the updates.
I am hoping to hear from someone that has fixed this same problem already.
