Hi, I have an MG5760 and had the same problem with both Easy Photo Print EX and My Image Garden using OSX 10.10. Couldn't print with error message 'Cannot print because a printer supported by this software is not installed' for My Image Garden when Print was selected and a similar message on Easy Photo Print EX that came up when I opened the software. Followed Canon's long involved instructions on deleting printers, restarting computer and installing software and drivers in a specific order - and it didn't work. Found your process PAHU and it worked instantly. Thank you so much. Tracey
