MSVCR80.dll error when using PowerPoint Viewer 2007

My wife has an Acer Laptop running Windows 7 64 bit and was trying to view Power Point files and kept getting the dll error. To solve the problem I uninstalled Power Point Viewer 2007, then went here Power Point Viewer 2010 download and installed the new version. Then go to Windows Update in the Control Panel and run it, there should be 3 or 4 updates for the Power Point app. Install the updates, shut down the computer so they install, restart and you should be good to go.
