just tried to upgrade zulu

I tried to upgrade Zulu and got the following error message during installation immediately after trying to set the admin password in the installation script.
<<Could not set admin password: java.io.FileNotFoundException: Public folder does not exist: C:\Users\Public.
Do you know what the problem could be?
