Method 2: Modify the registry

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. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

In Notepad, create a registry file (.reg) to change the Visio Viewer 2007 registry entries. To do this, follow these steps:

1.	Copy and then paste the following text in a new Notepad file: Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\.vsd] "Content Type"="application/vnd.ms-visio.viewer" @="VisioViewer.Viewer" [HKEY_CLASSES_ROOT\.vst] "Content Type"="application/vnd.ms-visio.viewer" @="VisioViewer.Viewer" [HKEY_CLASSES_ROOT\.vdx] "Content Type"="application/vnd.ms-visio.viewer" @="VisioViewer.Viewer" [HKEY_CLASSES_ROOT\.vss] "Content Type"="application/vnd.ms-visio.viewer" @="VisioViewer.Viewer" [HKEY_CLASSES_ROOT\.vst] "Content Type"="application/vnd.ms-visio.viewer" @="VisioViewer.Viewer" [HKEY_CLASSES_ROOT\.vsx] "Content Type"="application/vnd.ms-visio.viewer" @="VisioViewer.Viewer" [HKEY_CLASSES_ROOT\.vtx] "Content Type"="application/vnd.ms-visio.viewer" @="VisioViewer.Viewer"
2.	On the File menu, click Save As.
3.	Select a location to save the file.
4.	In the File name box, type Visioreg.reg.
5.	In the Save as type list, click Text Document (*.txt), and then click Save.
6.	On the File menu, click New.
7.	Copy and then paste the following text to the new Notepad file: @echo off reg delete "hkcr\.vdx" /f reg delete "hkcr\.vsd" /f reg delete "hkcr\.vss" /f reg delete "hkcr\.vst" /f reg delete "hkcr\.vsx" /f reg delete "hkcr\.vtx" /f regedit /s C:\Visioreg.reg Note: The last line of the file must include the full path and the file name of the .reg file that you saved in step 5.
8.	On the File menu, click Save As.
9.	Select a location to save the file.
10.	In the File name box, type Visiofix.bat.
11.	In the Save as type list, click Text Document (*.txt), and then click Save.
12.	In Windows Explorer, locate the folder in which you saved the Visiofix.bat file.
13.	Double-click Visiofix.bat.

After you complete method 2, when you double-click a Visio file, the file will only open in Visio Viewer. To edit a Visio file, you must start Visio, click Open on the File menu, and then locate the file that you want to edit.

You must reapply this workaround if Visio 2002 is repaired or if a service pack is applied.
