Install error, win10, 2019.33020

Windows 10 Pro
Build 2019.33020
The installation starts, shortly before it ends i get a pop up window saying:
Could not create file
C:\WINDOWS\installer{9E392D5C-06B4-412D-8659-C0CF1473
4E19}\touchdesigner.exe from script data. Error 112.

The installation then rolls back.

Any help appreciated!
