Fistful, Thank you for taking the time to develop this plugin.

When I search for this plugin in the plugin manager, it shows up but when you install it after taking the permission needed, Notepad restarts and appear again like I never did install anything, I did it twice without results.

Please try testing your plugin with the latest version of Notepad++ 7.6.6 build time 3Apr2019

Kind Regards,
Sello A.

Hm... I get the same result if I try to install it using the Plugin Admin (not the Plugin Manager) in a new Notepad++ installation. It's a pity Notepad++ doesn't show any message mentioning why it didn't install the plugin. :-(

I'll try to determine what's going wrong, and see if I can fix it.

The problem seems to be that the Plugins Admin doesn’t handle query string parameters properly; even the separators need to be URL-encoded for it to work.

I’ll update the PluginList (and [https://github.com/notepad-plus-plus/nppPluginList/issues/83#issuecomment-487057924|test them]) when I can, but this means they’ll only get published with the next version of Notepad++.

In the meantime, you can try to [Installation|install the plugin manually].

The problem originates with [https://github.com/notepad-plus-plus/wingup/issues/9|this bug] in Notepad++’s updater.

I’ve circumvented the problem for now by escaping the full download URLs. It works in the debug version, but we'll have to wait for the next release of Notepad++ to see if it really works in the final version as well. I’ll close this bug at that time (if I don’t forget).
