failed to create folder

This is typically an antivirus issue.  So please set an exception in your antivirus for EADesktop.exe.  You'll likely also need exceptions for TS4_x64, TS4_DX9_x64, and TS4_Launcher_x64.

If the exception doesn't help, uninstall the EA App with Revo Uninstaller (the free version is fine) and reinstall it, then try again, still adding the exception.  If that doesn't work either, disable your antivirus, temporarily, and try again.  You can reenable it as soon as you run the update.
