How do I uninstall demo projects before I update to 4.1?

Now that the 4.1 update is out, I’m trying to remove all stuff related to 4.0.2. I can see that some of the Marketplace demos has an upgraded version for 4.1. If I try to remove the old version by deleting the folder in my Unreal Projects folder, the launcher still lists it, buy with a repair notice. The launcher must somehow know what demos I installed. Where is that stored?

I think the launcher just checks online that you downloaded the files, so you can be sure you deleted them.

Hi peterpop,

The Launcher remembers the projects you have downloaded in the Manifest files which are located here:

C:\ProgramData\Epic\UnrealEngineLauncher\Data\Manifests

Removing the particular manifest files will clear all record of the associated project. However, be aware that the manifest files are not descriptive or user-friendly, and the only way to identify the associated project is by opening them in Notepad and looking for the project name.

Cheers

Thank you. Looks much cleaner now.
