Can't launch Warcraft III?

Some directories/files might not be created or created in a wrong way. A few antivirus programs may also delete the essential files falsely detecting them as viruses.

[Client] "Process failed to start: The directory is invalid" Message

This message indicates that the Client wasn't installed properly.

Solution

Remove the current Client and reinstall it using the newest installer.

[Client] "GProxy is missing" Message

This message usually means that gproxy.exe isn't present in the Client's directory. Due to the functionality of GProxy, some antivirus programs may falsely detect it as a virus and delete it automatically. The most known antivirus that does that is Avast.

Solution

Add gproxy.exe to the exception list of your antivirus and reinstall the Client.

[Client] "w3l.exe is missing" Message

In most cases it means that w3l.exe file is missing in your Warcraft III directory. The file is essential for letting you connect to our servers but it may also be wrongfuly detected as a virus since it is a "hack" which redirects the game to our PVPGN servers instead of the official ones.

Solution

Add w3l.exe to the exception list of your antivirus and reinstall the Client.

[W3] CD-Keys missing

The following message appears if your Warcraft III directory is missing the license keys:

Solutions

• Reinstall the Client and it will recreate the keys.
• Alternatively you may download our license keys and place them into your Warcraft III folder manually: roc.w3k tft.w3k

or copy-paste them into the fields:

ROC: F9R4Z2W92HYTV226Z2V2XZVDXG

TFT: VKKRWD6V8W2KPYCXYVE4YBX7MZ

• If you possess your own license keys, simply type them into the fields instead.
