If I understand you correctly, all you need do is “Uninstall” the analyzer using the Uninstall option in the analyzer’s popup menu:

1/ Click on the Extensions button to show the Extensions side bar.  
2/ Hover over the extension you want to uninstall.  
3/ Click the popup menu button (three vertical dots) for the extension  
4/ Click “Uninstall”

Thanks for your quickly reply.  
Actually, I know about uninstall ‘extension’ analyzer in extension tap.  
But I wanna delete ‘custom’ analyzer in Logic Pro software.  
It was clear for re-setup software, and re-initialize in analyzer.  
Really thanks for your comments.  
Have a good day.

Do you mean analyzers managed through the Preferences page (Edit/Settings… menu) about half way down the page?

Clearing the “Custom Low Level Analyzers” path then restarting Logic2 will remove custom low level analyzers. If you want to remove a specific custom low level analyzer you can remove the .dll file for the analyzer from that folder then restart Logic2.

Note that if you are developing an analyzer and you make changes to it, you must restart Logic2 for the new version to be loaded.
