Some things will cause Windower to crash. One of the main causes is updates to FFXI breaking plugins and Windower.

After a patch, if your game crashes on load, please check the Windower News Forum for news from us.

Disable any broken plugin in init.txt until it is fixed.

A few things are known to cause windower to crash.

• XFire - You can not use XFire with Windower & FFXI
• Steam - You can not launch Windower with Steam
• WindowsBlinds/AlienWare Skinning (Any 3rd Party windows skinning) - These will crash FFXI - Use uxtheme.dll hack or disable pol.exe from being skinned.
• ProcessGuard - Will likely cause problems with windower - Thats what processguard is designed to do, stop windower from doing what it does.
• Some virtual keyboards. (Like BizarroTrainer)

If you have crashes when hitting Play in POL on Vista, please try out the Windower 3.42.0 Beta.
