Every time I launch Aperture in 64 bit mode I get an error that says Aperture cannot be opened because of a problem. In the details it says Reason: no suitable image found. Did find: /Library/Frameworks/PluginManager.framework/Versions/B/PluginManager: no matching architecture in universal wrapper When I click the option to run in 32 bit mode it runs just fine. Does anyone have any suggestions on how to fix this? its version 3.1.3 and I have tried re-downloading from the Mac App store several times and get the same error.
