notepad++ plugin manager shows no available plugins

I find the reason.

My computer is in a LAN and the browser is using a proxy. I add the proxy for the plugin manager and update the plugin manager.

After all, it works.

Also, make sure the plugin manager is itself updated !

You will need to launch Notepad++ as an administrator because the plugin are saved/updated under %ProgramFiles/ which is protected

Go to Plugins / Plugin Manager / Tab Updates and check if plugin manager has an update. Relaunch and voilà.

If the all of the above fail, try this:

1. Manually download the plugin .
2. Then from menu settings → import → import plugin, navigate to the plugin (.dll) location.
3. Load the file.

Check the Plugin menu, the new plugin will be listed there.

I know this was answered a long time ago, but, a similarly-looking problem made me google, and land here.

Problem : Plugin Manager doesn't show in the Plugins Menu.

Why : You downloaded the 64-bit NPP version, and Plugin Manager doesn't support 64 Bit.

Solution : Uninstall, and Install 32 bit version.

Note : Directly from the download website, right next to the url it says that Plugin Manager won't work (lol), I didn't even read it just clicked 64-bit download, and while writing this post I figured that out. Anyhow if I missed it the first time, odds are someone else will also miss it hence my post.
