新規C++クラスを作成ができない

Hi.

That’s a new error.

Try the following step.

  1. Close unreal and visual studio;
  2. Go to your project folder;
  3. Delete the following selected folders and files:
  4. Right Click on your .uproject and generate your visual studio project file:
  5. Open your project’s solution (YourProject.sln);
  6. On visual studio press CTRL + F5.

In case it does not work, can you print your UpgradeLog.htm.

Bye.
