I need to convert graphics that were created in Powerpoint to PNG files with 96 DPI resolution. This shouldn't be hard since Powerpoint has two ways to set this:

• File > Options > Advanced > Image Size and Quality > Set default target output to [x]
  
• Modifying the Registry and setting this number (for Powerpoint 2010): HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\P owerPoint\Options\ExportBitmapResolution

The trouble is, neither of these works for me. No matter what I do, I get output at 220. My registry setting clearly says 96, but this does not affect the program. An IT support person helped me change the registry but had no suggestions about how to make this work. The setting done within the program similarly has no effect. Can anyone tell me why my setting does not take?


PS: the heading shows me as a novice, but this isn't the case.
