Hi Joseph,
I noticed you have posted under PayPlans earlier(
http://take.ms/3AtcU). May I know which extension you are having issues?
I have temporarily moved this to EasySocial.
Here is the documentation for installing EasySocial:
https://stackideas.com/docs/easysocial/administrators/welcome/installing-easysocial
I have managed to help you install EasySocial using the launcher without any issues. I use the steps as outlined in the documentation.
EDIT: I noticed you mentioned uploading the launcher through ftp. May I know the reason you did not upload the launcher package at Joomla's extension installer(
