The first time that Microsoft Picture Manager is launched, there is a request to select the file types that will default to opening in Picture Manager 2010. In addition, there is an option on the Tools menu to select file types to open in Microsoft Picture Manager by default. However, when one of these graphics files (such as .JPG) is opened from the Windows Desktop or another folder location, it does not open in Microsoft Picture Manager. It opens in another application such as the Windows Photo Gallery.
If Microsoft Picture Manager is installed as part of an Office product that uses the Microsoft Office Click-to-Run 2010 technology, it is installed in a virtual environment. Because of the virtual environment, the file association ownership is not written to the Windows registry location that controls which application opens the file.
To open the graphics file, it is necessary to launch the Microsoft Picture Manager application first. Then locate the file to be opened in the Picture Shortcuts pane of Picture Manager. Double-clicking the image in the main window will open the image in Picture Manager.
