I downloaded Notepad++ from https://notepad-plus-plus.org/repository/7.x/7.5.1/npp.7.5.1.Installer.x64.exe.
And I installed the same. Now I need to install few plugi
Notepad v7.6 includes a Plugin Admin and from this you can install Plugin Manager(note1) but it doesn't work fine with npp v7.6(note2)
On the other hand Plugin Admin is only available on NPP "Setup version" and after following conditions
Plugin Admin will place plugins at C:\ProgramData\Notepad++\plugins
(note1)Installation from Plugin Admin is not complete and \updater\gpup.exe is missing (note2) Plugin manager is not using new plugins path and folder structure; from version 7.6 npp Plugins will be stored in individual folders (having same name than file.dll)
If you want to use npp7.6 portable, you can copy updater folder from Setup version, copy plugins from Setup version, or copy Plugins from npp v<7.6 and place each one in a individual folder.
