System OS/device including version: Windows 8.1 64bit, 8GB AMD FX 6350 6 core .NET framework installed as of 1.21.19 .NET 4.7.2 Reg key: Release REG_DWORD 461814 Nuget 4.92

Describe the bug For us an uninstall-Reinstall of Xenko and the launcher resulted in:

1. Local dev copy of Xenko 3.0.0.6 that was previously building and working exits with an invalid operation in mscorlib under debug in VS2017, built but would not run. XenkoGameStudio.exe shows in the process list but shuts down without window display.

2. Clean reinstall (multiple times) of the Xenko launcher v.3.0.5 and attempted install of 3.0.0.6 or 3.1beta presents with the error shown in the launcher screenshot and below.

To Reproduce Steps to reproduce the behavior:

1. Download the launcher and attempt to install Xenko following an uninstall of Xenko (3.0.0.6 and 3.1 beta)

Expected behavior A proper install without errors.

Additional context Googling the error “Number of entries expected in End Of Central Directory does not correspond to number of entries in Central Directory.” shows similar issues with downloading/uploading zip files.

I will reopen to do the following improvement on Xenko side: When Xenko or Xenko Launcher is started, check all Xenko package sources and delete the ones for which folder doesn’t exist anymore.

OK thanks for the update! I will think about automatically purging non-existant Xenko feeds automatically.
