Most of the people I work with are used to handling AutoCad drawings, but not necessarily Microsoft Visio files. Today someone passed me a .vsd file that they needed to have printed, but were not sure which application to use. I didn’t have Visio installed on my laptop so I thought the quickest and easiest thing to do was to install the Visio Viewer. First I tried Visio Viewer 2007 and then Visio Viewer 2003. Neither worked so I did a quick search. It seems that a Windows Update called Cumulative Security Update of ActiveX Kill Bits disables Visio Viewer. The solution is to go to Add Remove Programs, find the KB973525 update (be sure to check the box that says show updates), and remove it. After uninstalling the update Visio Viewer worked and I printed the drawing.
