Authorization process failed

[PatriceFillon]

Hi everyone,

I was using ArcMap 10.7 until yesterday and I receive a license ArcGIS Pro Advanced single user key from my organization. I am facing this issue just after the authorization step: "the authorization process failed to complete successfully core licenses from a prior version exist on this machine"

https://drive.google.com/file/d/1wkfSzDjU3yvGDPHDmJhknBEOT_YZBF3t/view?usp=sharing is the authorization screenshot

https://drive.google.com/file/d/1wRemUyBQe7YgFzirN6BNlsNnUplxdsJ0/view?usp=sharing is the failed process.

Any clue, advice? Thanks a lot in advance and best.

Was your old license deauthorized? 

You can try going into windows registry editor - Esri- AGOL for Pro - Sign in - change value from 1 to 0
