I just installed the Visio 2010 viewer.

How do I now make this viewer to open if I double click a VSD files? Every time I do so only my web browser (Opera) is started - but it is not associated with the VSD file extension.

I tried to manually assign VSD files to the viewer but I wasn't able to find the viewer executable file.

Despite the name, Visio 2010 viewer, is not a stand-alone application, but it is a plug-in to Internet Explorer. As such it does not really work well. For instance, for printing properly, there is often no other way than to zoom, take a screenshot, crop (in, say, Paint) and print out through some other program, say Word. – Peter Mortensen Apr 19 '13 at 11:18

The site to which you linked says the viewer only works in Internet Explorer 5 through 8.

Visio Viewer is implemented as an ActiveX control that loads and renders Visio drawings inside Internet Explorer.

This download works with the following program: Microsoft Internet Explorer 5, 6, 7, or 8.

If I associate VSD files with IE then Opera comes up as it is my default web browser. Stupid IE. If I start iexplore.exe from command line with the VSD as parameter it works!? – Robert Oct 19 '11 at 17:25

I found a solution:

The problem is that the registry entries are incorrectly set by the Visio Viewer installer.

You have to delete the registry key


Then you have to add "%1" to the value of


so that it looks as follows:

"C:\Program Files\Internet Explorer\iexplore.exe" -nohome "%1"

Make sure that the "Microsfot Visio Document" add-on is not disabled in Internet Explorer. You can see the installed add-ons in Internet Explorer, under:

Tools button (upper right hand corner) > Internet Options > Programs tab > "manage add-ons" button
