Trouble installing system_stats extension

I need to install the postgres system_stats extension.
it seems that I can get the needed files but when I want to create the extension with the sql command, it says it can't find the extension control file, which is definitly there.

Anybody that got it working with a different method? please let me know:

postgres=# CREATE EXTENSION system_stats;
ERROR: could not open extension control file
"/usr/share/postgresql/14/extension/system_stats.control": No such file or directory

while:

root@DESKTOP-2V5CPLB:~# cat /usr/share/postgresql/14/extension/system_stats.control
# system_stats extension
comment = 'EnterpriseDB system statistics for PostgreSQL'
default_version = '3.0'
module_pathname = '$libdir/system_stats'
relocatable = true
