Let me fix it myself

When you configure Dreamweaver as the default XML editor, and then you try to open an XML file, this creates a conflict with Windows Vista. Adobe has created a registry change that resolves this issue.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

Dreamweaver 8 was released more than a year before Windows Vista became publicly available. Therefore, Dreamweaver 8 does not officially support Windows Vista. The next version of Dreamweaver will be certified to run on Windows Vista.
