Click save (not save as). Rename the file to something more appropriate like "w3extensionfix.reg". Double-click the file and choose to add it to the registry.

This modified file should now re-associate Warcraft with the following files
- wai (WorldEdit AI)
- w3g (Warcraft Replay)
- w3n (Warcraft Campaign)
- w3m (Warcraft Map)
- w3x (Warcraft Expansion Map)

In order for it to work Windows must be reloaded. You can do this by either relogging into Windows, or restarting your computer.

NOTE: This assumes Warcraft is installed at the default location of C:\Program Files (x86)\Warcraft III. If you have it installed elsewhere, it will not work (and incorrectly assign some Warcraft extensions).

If You are using 32bit windows and You have same problems try Warcraft III Registry Fixer.
