LR 12.53 Patch 4 putting setup.dll into registry to run

I have mentioned this before somewhere, but what I am still seeing my issue in Patch 4 which was released recently.

When I install Patch 4 over Patch 3 on my machine it came up saying that I need to reboot my machine. When I rebooted it an error came up saying that a dll file could not be executed.

I see in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\ that there is a new extry
Name: HPPrequisite
Data: "C:\Temp\LR_03639\setup.dll"

Why is the .exe file not in the Run?
Is my machine setup incorrectly not to run the .dll file?
