Blender 2.93.3 > says it's installed but not listed in addons

[quadcom]

Installed 2.93.3 and manually installed the importer/exporter.

Console window says it was installed but it is not in the list of installed addons nor does it show up in the import/export dialogs.

Doesn't seem to be working.

Have you changed the selection for the add-ons to include "Testing" ? I had to turn that on before it would appear.

Until this is accepted as a community add-on here, the "testing" add-ons will need to be activated in order to load this.

I also am having this problem. Installed from zip, it says it was successful in the console, and I can find it under my user scripts. But even though I refresh and enable testing, nothing. Any ideas or suggestions?

I had a similar issue when using Blender 3.3, and installed it using the version found here:

In 3.5 release the Testing tab is hidden. I used these steps to re-enable the tab's visibility.

The answer from @numanair works perfect in blender 3.5: If the Testing-Tab in add-ons is not visible, simply go to [blender-installation]/scripts/startup/bl_ui/__init__.py and make sure the Testing tab is "enabled" for your installation.

This can be done by commenting line 149 out and un-indent line 150 like so:

After that, the Testing-Tab is visible again:
