There's a whole forum about Warcraft III (and Reforged). This is only open for issues relating to computers (such as Windows or hardware problems).
You might want to write there or maybe the moderator will move your post here:
Discuss topics related to Blizzard's Warcraft universe, including Warcraft I, II and III. Ask questions about anything not covered in other forums. In this forum you can also discuss multiplayer, find others to play with and set up game arrangements.

Other than that, your game installation seems to be broken if I see the picture. Most notably, the registry ones.
What game version are you currently using?
