Open plugin manager

1. Install from ZIP
2. Browse to plugin zipfile
3. Install plugin

I get:

pyplugin_installer.instance().installFromZipFile('C:\Users\tchadwin\Downloads\qgis-latlontools-plugin.zip')

It works with other plugins, so seems something specific to the plugins you tested.

• status_id was changed from Open to Feedback

If you can upload a known working zip (or link to one), I can test that.

Tom, could you please verify it tomorrow with the real build and reopen if necessary? I did some dummy tests and I believe it will work.

For now, you can install from other directories - just avoid the "\U" special character (like in "C:\Users").

Ah, and when investigating the issue, I found a few other bugs and created #25523 . It seems the newly installed plugin is not included to the installed plugins list, so you can't tick the checkbox to enable it (btw. the fastest way to refresh the list is the Settings tab -> "Reload all repositories"). Feel free to add more annoying bugs there - I'm going to get down to it in a few days.
