ISS 2020 windows install fails due to existing Advisor 2019

I am attempting to install Intel System Studio 2020 on Windows for Windows target.  The installer fails when it discovers an existing Advisor 2019 with the following message:

Intel(R) Advisor 2019 is installed on your system. This version of the Intel(R) System Studio 2020 Ultimate Edition for Windows* software is incompatible with Intel(R) Advisor 2019. Please install this software on a fresh Windows system.

I uninstalled Advisor 2019, rebooted, but the ISS 2020 installer still fails with the same message.  I have gone through registry and discovered several references to Advisor 2019 and have removed those - but all further attempts to install ISS 2020 fail with the same message.

I then fully uninstalled ISS 2019 and attempted the ISS 2020 install - still no success.

Any assistance on how to install ISS 2020 without...

"a fresh Windows system"

...(does that really mean a system with no previous Intel installations or no other software?) will be greatly appreciated.

Thank you in advance for any assistance.

After several days of combing through the windows registry, and researching how Windows handles installations, I stumbled upon what might have been the issue.

I noticed in one of the uninstall keys, a reference to msi packages, followed that thought to this site:

how to list installed applications from a command line

That led me to the C:\Windows\Installer directory from which I searched for the words "advisor 2019", which led me to two .msi files and two .tmp files.

After deleting those 4 files, the installer for ISS 2020 no longer advised me that Advisor 2019 was installed (although it really wasn't) and the ISS 2020 installation completed successfully!
