Sorry, didn't read the thread correctly!
If it's not showing up in the plug in menu, make sure you installed correctly the VST or VST3 or AU extension for Analog Lab, by checking those paths:
If one of the extension is installed, I'll invite you to follow this procedure:
1/ Launch Ableton
2/ Press 'Cmd' + ',' (MAC)
3/ Click on the 'File Folder' tab
4/ Check the 'Plug-Ins Sources' section and make sure the 'Use VST Plug-In System Folder' is set to 'On'
5/ If the mention is already set to 'On', please, click on Rescan
