How to open .WIZ files on Windows
To open .WIZ files on Windows, if you trust the source, open the relevant Microsoft application (commonly Microsoft Word), then use File → Open to select the .wiz file (opening it from inside the app is often more reliable than double-clicking).
Step-by-step instructions
- If you trust the source, open the relevant Microsoft application (commonly Microsoft Word), then use File → Open to select the .wiz file (opening it from inside the app is often more reliable than double-clicking).
- If Windows prompts you to choose an app, select Microsoft Word (or the Microsoft program that the wizard belongs to) and set it as the default only if you frequently work with .wiz files from trusted sources.
Common issues
Windows opens the file in the wrong app (or asks which app to use)
File associations may not be set for .wiz, or the system may treat it like a Word-related type depending on configuration.
- Right-click the .wiz file → Open with → Choose another app → select the Microsoft application that should handle it (often Microsoft Word).
- If you manage file associations centrally, review Windows file type association settings (including the 'Content Type' value) for the .wiz extension.
The wizard does not run or content appears missing
A .wiz file is typically meant to be used by a specific Microsoft program/version; opening it like a normal document may not execute the wizard flow or may not load the expected resources.
- Open the .wiz from within the application it was designed for (for example, Microsoft Word) rather than double-clicking it.
- If you have multiple Office versions, try opening it with the version closest to the era it came from (older wizard files can be version-sensitive).
Macro/security warnings appear in Microsoft Office
FileInfo notes .wiz files can contain macros; Office may block or warn about macro-enabled content depending on your security settings and the file’s origin.
- Do not enable macros unless you trust the publisher/source and understand what the wizard will do.
- If you must use it, place the file in a trusted location only when appropriate for your organization’s security policy, then reopen it in the Microsoft app.
