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.

Could you give us the list of nuget package sources currently existing and activated?

In Visual Studio, go to Tools > Options command and scroll to NuGet Package Manager, then select Package Sources.

Package sources

Also the latest master does build, after waiting 5 min as DiegoBM suggested but when XenkoGameStudio.exe is run a dialog box pops up that then automatically opens a text editor with a similar central directory error.

Even with a fresh reinstall of the launcher it seems to still end up with these errors.
Will try deselecting the other two local sources... is this how Xenko auto detects installed versions??

[xen2]

What happens if you delete xenko\xenko (4th source)? (not only uncheck but delete with X button)
If not enough, pleas do that also with xenko (5th source) and then xenko dev (3rd source)

[aurodev]

After deselecting the 2 local /Document sources and a rebuild all of the latest master XenkoGameStudio.exe runs, does the privacy acceptance box then shuts down and the error popup shows.
nuget_error2.txt

Will try with the other sources deleted and post that tomorrow...

[aurodev]

A little early...

You were right. Deleting the 3 local sources worked.

Will try reinstalling the launcher tomorrow.

[xen2]

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

[aurodev]

Launcher and GameStudio now behave normally.

[xen2]

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.
