I have ACDSee free browser running on Lion. I installed it on Mavericks but it won't run. From some reading on the net I've discovered it is 32 bit. When I go to 'get info' there is no check box option for running it in 32 bit. I'm wondering if there is a workaround to force Mavericks to run it. Right now if I click on it in the app folder, the icon shows up on the dock for a second then disappears and nothing else happens.
