Ok, I can find NOTHING wrong with what we sent you. I installed 9.1.6, then updated using your update file. No problems whatsoever.
Seeing I have been wrong once before so far, I did send you another install with a license issue date of Aug/1 to try, but I doubt it will change anything. Note that the download link is different. You can still download the original update I sent you.
Here's what I would like to try next. Delete logic.license and logic.exe from c:\program files (x86)\logic LOGic should no longer run of course. Wait a few minutes to make sure that they don't magically reappear. Then install one of the updates. That will get back the new logic.license and logic.exe.
My theory is that SOMETHING is protecting your old copy of LOGic.exe (version .1.6). Some sort of automatic backup software, a virus protector, or....? But I have never run into this before in our 30 years of doing this.
You could also temporarily disable any virus protection, Google Drive etc., or use MSCONFIG to do a clean startup. Type {WinKey+R} and type in MSCONFIG
Do a Diagnostic Startup.
I can log in and take a look.

Call the office number at the top of the page. If I am out it will forward to my cell phone. If I don't answer, leave a message and I will call you back within 15 minutes or so. We can set up a time that is good for you.
Tnx & 73,
