pgAdmin 4 not installed

Hello,

PgAdmin installer taken from https://www.postgresql.org/ftp/pgadmin/pgadmin4/v8.12/windows/ and run on Windows 10 does not install pgAdmi at all ( no shortcut to exe file, no "pgAdmin 4" folder in C:\Users\<myuser>\AppData\Local\Programs ):

1) When run as administrator then message that installation has successfully finished but this is not true

2) When run as current user (non admin of local machine) then ends up with "Internal error: Failed to expand "group" constant" error message

Regards
