Hey -

Thanks for your post. This is a known bug that is currently being investigated and should be fixed in an a future update to the engine.

Hello :diamonds::diamonds:STAFF,

Seriously , This is a known bug ? ôÔ
I solved the issue by myself .

How ?
In error message , we can see all dependency that i deleted and hit Verifying Unreal engine via the launcher.

I deleted all repertory below :

\4.7\Engine\**Source**
\4.7\Engine\Binaries\**DotNet**

Thank You

Delete all repertory below :

  \4.7\Engine\**Source**
  \4.7\Engine\Binaries\**DotNet**

Force Verifying from the Launcher and download all deleted folder. Problem Solved

Hey , how do you force your launcher to verify? I don’t see any options from the actual launcher.

Hey Griffinstein-

On the Library tab of the launcher if you click the drop down arrow next to Launch for an engine version you will see the option to Verify that version.
