I have a brand new build running the may update for Windows 10, 1903.  
 
I have installed DGTuner.  The software is so picky.  After installing it would complain to close other "3d" programs, the EPIC launcher.  I close that, then DGTuner opens.  From there I am able to adjust my EVGA GPU and case.
 
When I reboot, Windows starts booting, and my RGB fans start the color breathing effect.  Then stops after a few seconds and stays at a static color.  DGTuner says it needs permission to run and I have to click an allow button from Windows.  By then the RBG fans and case all stop and stay at one color.  I then need to open DGTuner from the tray and click on EVGA sync again for it to work.  This fixes it, until the next reboot.  Then it all happens again.
 
I've uninstalled and reinstalled, and no luck.
 
Is there a fix for this?  This case seems worthless to have all of these features when  the software is unreliable.  That's not even to mention the hassle of merely finding the software on this website, and then having to register the case just to get a software package.  The whole process seems overly convoluted.  What good is the built in RGB hub if it's unreliable?  I am starting to regret my decision to purchase this case, and should have went with the NZXT I was eyeing up.  I even spent the extra $30 on the vertical GPU mounting bracket.  Of all the EVGA products I've bought, this is the only one that frustrated me this badly.  I've never had to contact support or write a forum post until now.
 
And, yes, I have the sata connector and USB plugged in.
