What I’ve done before to avoid this issue is you can rename your plugin. For example the installer removes DSpellCheck.dll I’ve just renamed it to DSpellCheck2.dll and it never warns me about it again :)
I did a few tests with BOM files and it seems that now “Encode in UTF-8” does remove the BOM. This makes total sense but it turned the previous logic upside down.
The problem is the Plugin Manager itself is not 64bit. There are a few 64bit plugins currently available. @Sai-Prasanth Your best option is to just manually copy any DLLs into the plugins directory of Notepad++. Even with older versions of Notepad++ I’ve never had luck trying to use the menu to import plugins.
I run Notepad++ on Linux with the help of “Wine” (originally an acronym for “Wine Is Not an Emulator”) it works great too! have used NP++ on Windows since it was new !
It’s still my favorite editor of all time.
