Problem with plugins and PHP

Hi. I have some problems with the theme plugins. I’ve follow the instructions from Github (manual instalation). I see the plugin in the gallery and in the installed plugins, but I can’t select them in the apearence theme (the don’t appear).
I´m working with windows 10 and I had some alerts “El comando tar no está disponible. Configúrelo correctamente en su “””. So I got a program PeaZip to compress with .TAR extensions.
I’ve also cheked in the forum Plugins installation problems in OJS The PHP libraries version is 7.3.12, could this be the problem?

Thank you!
