What in the hell is going on! 😡 🤬 - Error IS-0007 and others.

It’s not just one plug-in it seems to be pretty much ALL of them! Projects don’t bloody well appear in the launcher so take a guess - yeah you can’t bloody ADD to Project because it can’t see any!

It is NOT just 5.8.4 it is also 5.7.4 too!

My computer is COMPLETELY clean as in fresh windows install and an e-mail client + anti-virus. So they can bugger off with trying to suggest that it is anything to do with a bad Windows install or corrupt system. It was doing this yesterday which is why I fresh installed this computer to check if it was due to a corrupt system or bad Windows update. Though it could still be due to latest Windows updates???

This is un-acceptable!!! Also typical from Epic that they don’t actually seem to use their own software at all! Why the hell there are no filters for showing only plug-ins that require updating for instance. Not to mention NOT being able to work on ANY projects and using the bloody plug-ins I have spent so bloody much money on!!!

The biggest let down with this situation is my “ZibraAI” VDB compression plug-in! I am so damned angry with this whole situation! 😡🤬

It seems that the projects are now appearing in the “Launcher” so I can at least “Add to Project” now! 🙂 - Still no plug-in installation working!

Here is the fix from another of my posts to the forums 😊 from @Flak for anyone that is reading here and that has not found a fix:

Your screenshot helped here. We should have a fix for the plugin issue in the next version. In the meantime, could you try these steps as a workaround?

1. Fully exit the launcher from the system tray.
2. Go to `C:\ProgramData\Epic\EpicGamesLauncher\Data\`. The ProgramData folder is hidden by default.
3. Create a new folder named `Manifests`, and inside it a folder named `Pending`, so you have `C:\ProgramData\Epic\EpicGamesLauncher\Data\Manifests\Pending`.
4. Start the launcher and try installing the plugin again.
