Launcher Serialization Error

“Serialization Error: Action Needed
Corrupt data found, please verify your installation.”

I suddenly got this notification when trying to launch the Epic games launcher. I have uninstalled and reinstalled the launcher twice and each time received the same error when the launcher attempts to open after installing.

The log file of the most recent attempt:

Hello Chaelmed,

Please visit http://help.epicgames.com/ for technical support, here you can find information and solutions for common issues, as well as a contact form if you still need additional assistance. Thanks!

same problem here.

So I found out the answer was simple. Turns out if you ever installed Unreal and you later have your environment Temp & TMP paths changed at all(probably to free up space on your C:), then the launcher will fail. You can test this by making another user, and if the launcher works on that account and not yours then you can be sure it the environment variable. Just go to your system settings and set them both back to: %USERPROFILE%\AppData\Local\Temp

After a restart that should fix the problem.
