I ran into an issue today where I was unable to get the Visio Viewer 2007 working on my Windows 7 (64bit) installation. After some digging around on Google, I discovered this post that outlines the install the steps below. I added the direct links to the downloads for ease of use.
- Install Visio Viewer 2007
- Install Visio Viewer 2007 Service Pack 2 (SP2)
- Re-install Security Update for Microsoft Office Visio Viewer 2007 (KB973709)
After I followed these steps my Visio Viewer 2007 started working correctly on Windows 7.
