I installed the quickstart joomla named pitech_quickstart_j4.zip and it worked and now I am trying to install the component named com_splms_fullpackage_v4.0.4 zip file but am getting these errors:

JInstaller: :Install: Can't find Joomla XML setup file. JInstaller: :Install: Can't find XML setup file. You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '' at line 2

Can you pls tell me what I'm doing wrong?

I purchased the LMS features specifically and I need the com_splms_fullpackage_v4.0.4 zip file to install.

Any help is very much appreciated. Thanks much.
