Not a Question but Hi,My Cc isn’t showing up in the game with the Package Installer...
Firstly, is custom content enabled in your game? Also, in the documents folder where your CC goes, is your Downloads folder spelled with a capital 'D'?
Plus, when it comes to package installer, if it's a .sims2pack, you have to double click on it for it to install.
Some content is packaged and needs a third party product like WinRAR or 7-zip to unzip the files for it show up.
Some CC requires an external mesh or a specific pack for it to show up. So make sure to double check to see if a mesh is required for your content to show up.
Here's some extra sites that go into more details about certain issues:
