Canon Digital Photo Professional 4.3.0 install fails under MacOS 10.10.5
New version of this utility downloads OK, unzips apparently correctly and the .dmg file mounts as a disk image with a window that shows an install application icon. A double-click on the application yields a progress bar that says that files are being expanded, but then nothing more happens.
I have done disk permission repairs and turned-off all my anti-virus software to no avail.
Canon support thinks it is a Mac Yosemite (10.10.5) issue. Software is a direct download from the Canon USA site for DPP 4.3.0. This same behavior is seen for one or two other downloads I have tried from the site. Has anyone ever heard of anything like this? Got any suggestions?
