…this issue will probably disapear when plugins will be available in both 32 and 64
There are already 64 bit plugins available (for about to 1.5 years). The 64 bit plugin manager is obtainable here, take PluginManager_v1.4.12_x64.zip. Please note: Plugin Manager is currently only usable with Notepad++ versions prior to v7.6 since the location where plugins have to be installed has been changed in this version.
N++ should be able to manage both 32and 64b pluggins and probably also local and user plugin folder
I’m afraid that you will never get this features. I would appreciate them too but @donho , the developer of Notepad++, has decided to simplify things and to reduce the number of installation variants.
