[New-bugs-announce] [issue29702] Error 0x80070003: Failed to launch elevated child process

New submission from Armen Levonian:

For some reason, after uninstalling Python 3.5.2 on my Windows 10 (64 bit - latest version), I am no longer able to install any new version of Python after version 3.4.3

I keep getting the failure to elevate privileges. I have of course tried to run the installer as Admin, or even launch a command prompt as admin or powershell as admin then run the installer with no luck. 

Disabling Windows Defender did not help.

I have also lowered UAC all the way down, to no reporting, still no luck.

The log file attached is for the 64 bit installer for 3.5.3 but I get identical results with the 32 bit installers for version 3.5.2 and 3.5.1.

I can install latest Anaconda and also Python 3.4.3 without issues.

I also had no problem installing 3.5.3 on another of my machines with same Windows 10 (64 bit) and that machine accepts the install without issues.

Once again, I had version 3.5.2 running fine until I uninstalled it to upgrade.
