Hey folks,
For most players who are having this error message, we’ve found that one of the following things is most often true:
- The computer does not meet the minimum system requirements
- The operating system or graphics drivers are out of date
- A security program is blocking the game client from launching
- A different background application is blocking the game client from launching - particularly ones with overlays or which modify game/mouse/graphics driver settings
- There is corruption of your admin account or registry.
There are also a couple bugs which we’re looking into which may cause the game to crash on launch with certain machines, but the steps above should still fix most situations. A work around was mentioned earlier to set the game into windowed mode. While we don’t consider this a “fix” in the event you’re running into a bug, here’s a better way to put the game in windowed mode. I’ll update the post above with these better steps, since the preferences file is not created until the game successfully launches:
- Open your
Battle.net applicationand select theWarcraft IIItab - Click the
Optionsgear (above the news widget) and clickGame Settings - Scroll down to
Warcraft IIIin the list and click theadditional command line argumentsbox - In the blank that pops up, add
-windowmode windowed - Click
Doneand retest the game
Hopefully this helps with most of you. Please keep in mind that beyond this, you probably have an issue that will need us to troubleshoot it individually. If nothing in this post works, please create your own thread or contact support.
