If you installed a third-party component but Plesk does not recognize it
and does not show it in Server Components, you can check the Plesk
registry subtree:
HKEY_LOCAL_MACHINESOFTWAREPLESKPSA ConfigConfigPackages
Check if the necessary component is present there. If everything is
correct, you need to check whether all required *.dll files are present
in the %plesk_bin% folder. You can find the *.dll name in the following
key:
HKEY_LOCAL_MACHINESOFTWAREPLESKPSA
ConfigConfigPackagespackage.namecomponent.namedll
For example:
HKEY_LOCAL_MACHINESOFTWAREPLESKPSA
ConfigConfigPackagesmailservermailenabledll == ‘C:Program
Files%plesk_dir%adminbinmailenableproviderw.dll’
If the *.dll is not present in %plesk_bin% you need to locate it and
copy to the %plesk_bin% folder. After that, log in to Server
Administration Panel and click Tools & Settings > Server
Components > Refresh. The component should appear.
