The issue can also occur when you open an embedded or linked Office file in an Office application. For example, you have a Visio object embedded in a Word document. When you try to open the Visio object, you receive a similar error message in Word. To resolve this issue, you must change the File Block settings in the application that owns the blocked file type. In this example, you must change the File Block settings in Visio instead of in Word. If the error message mentions Excel file type, go to Excel to change the File Block settings.
The following tables contain the all DWORD values that you can add to the FileOpenBlock subkey and the corresponding file types.
