WC3 Reforged Installation

Legacy Games Tech Support
1

Hello All,

I have been trying to play WC3 Reforged for at least 7 days with no avail.

Endless back and forth with Blizzard support has proven that they basically have zero ability to troubleshoot.

Problem :

Every time I press play through battle.net I get the error message

“Game data is unable to load and must be repaired. Please run Blizzard app to repair the game. If the problem persists, try reinstalling the game”

Error log :

What I have tried so far :

  1. Repaired like 30 times
  2. Re-installed like 10 times.
  3. Re-installed without logging into battle.net app.
  4. Changed my connection
  5. Changed installation folders.
  6. Disabled Firewall and Windows Defender.
  7. Flushed DNS.
  8. Switched regions from battle.net and game regions.
  9. Cut 2 cases with Blizzard. Zero help. AI responses.
  10. Disabled background applications

My PC Specs :

I would really appreciate any help I can get to play the game.
