ThinInstaller with SCCM - Progress pauses at "Displaying License Notice"

Question

I have been using ThinInstaller successfully during my ConfigMgr task sequences for some time now, but after updating UpdateRetriever and ThinInstaller to the most recent versions, and adding some content to my repository, I have the following issue:
The ThinInstaller process seems to hang at a specific step when run during my task sequences. The task sequence kicks off my ThinInstaller package, which installs the ThinInstaller files locally, and then runs a command to point to my driver repository. The specific command run is:
"PathToThinInstaller\ThinInstaller.exe" /CM -search A -action INSTALL -repository "PathToRepository" -noicon -includerebootpackages 1,3,4 -showprogress -noreboot
And it seems like the ThinInstaller application scans the local system and determines which updates are required. However, until I press "F8" (and only F8), there is no GUI displayed (even though I am using the -showprogress command line argument) and no driver packages are downloaded or installed. Looking at the log files on such a machine, I see the progress pause at a specific step. Quick note: It's just a coincidence in the logs below that I hit F8 about an hour after the progress paused:

Based on that snippet, progress paused around 4:15, with the last step being "Displaying License Notice". I let the machine go until about 5:15, then pressed F8 (to launch a debug command prompt window in the ConfigMgr task sequence) and immediately after pressing F8, the ThinInstaller UI appears and ThinInstaller progress resumes with the "Settings -ShowProgress Install Progress screen" log entry. When I press F8, there is no license prompt displayed or anything requiring user interaction - it just suddenly starts running again, and will eventually run to successful completion. I can confirm that the ThinInstaller.exe.configuration XML file on the workstations I'm building is still in the default configuration, with DISPLAYLICENSENOTICE = NO and IGNORELOCALLICENSE=YES.
The curious thing is that I can run this exact package manually, using the exact same script that is called by the ConfigMgr task sequence, and it runs to completion, no issues, no license prompts, no need for user intervention, nothing. I did not make any changes to the command lines being used by my scripts - only changed the versions of UpdateRetriever and ThinInstaller. And technically, my task sequences still work, it's just very annoying to have to watch for this step in the process and press F8 to keep it from sitting and doing nothing.
Has anyone else seen anything like this after an upgrade to new UpdateRetriever/ThinInstaller versions?

Unfortunately, these page numbers do not correspond to anything in the v.4 TVSU deployment guide.  I've re-read all of the applicable areas in the guide, but still cannot get past one thing.  The guide does NOT seem to give a way to avoid ALL license messages.
Due to the fact that TVSU does not load the registry parameters on first startup, I've resorted to a method given by several others on the internet that involves (using a script launched via SCCM) (script shown below) starting TVSU, using TASKKILL to kill the process, and then making registry changes to set parameters.  I then run a second step that launches TVSU again via command line which should do the 2nd launch of TVSU without having any popups.  HOWEVER, I still get one license popup.  It seems you do not get credit for the first launch when you kill the process without agreeing to the license.
Here is the code:
First step script:
cmd /c "C:\program files (x86)\Lenovo\System Update\tvsu.exe"
cmd /c TASKKILL /F /IM tvsukernel.exe
REG ADD "HKLM\SOFTWARE\Lenovo\System Update\Preferences\UserSettings\General" /v ExtrasTab /t REG_SZ /d NO /f
REG ADD "HKLM\SOFTWARE\Lenovo\System Update\Preferences\UserSettings\General" /v IgnoreLocalLicense /t REG_SZ /d YES /f
REG ADD "HKLM\SOFTWARE\Lenovo\System Update\Preferences\UserSettings\General" /v DisplayLicenseNotice /t REG_SZ /d NO /f
REG ADD "HKLM\SOFTWARE\Lenovo\System Update\Preferences\UserSettings\General" /v DisplayLicenseNoticeSU /t REG_SZ /d NO /f
Second step command line:
cmd.exe /c tvsu.exe /CM -search A -action INSTALL -repository \\server\share -includerebootpackages 1,3,4 -noreboot -noicon
 When I check the tvsu_log, I see that when the license dialog pops up, the log file reads, "Message: Display pick list license notice? YES"
This is the license notice I need to get past.  Is there any way to suppress this license notice, given that I've already made the registry changes detailed above?
