How to access Digital Photo Professional 4 App by Canon on my mac OS Mojavi

I have a lot of edited pictures on Digital Photo Professional 4 App by Canon which I can no longer have access to, this is the error message I get:

The last time you opened Digital Photo Professional 4, it unexpectedly quit while reopening windows. Do you want to try to reopen its windows again?

And then the quit unexpectedly and that the report will be sent to Apple! appears.

It has been over a week and I still have no way of opening DPP4?? Please help.

Disclaimer: I don't use DPP4, but am definitely familiar with macOS as well as software on that platform. So here's a possible fix.

From Finder, hold down the option-key and while that is pressed, click on the Go menu and then select the "Library" menu item. That menu item only shows when the option-key is pressed. A Finder window for "Library" should then appear.
There's a subfolder inside "Library" named "Preferences". Try to find either a file or folder that starts with "DPP" or perhaps "com.canon".
Right-click (or control-click on that item and select "Compress <filename>". This will create a ZIP file (basically you're backing up the original data).
Delete the folder or file that you right-clicked on in step #3.
Relaunch DPP

My thought is that the application preferences have become corrupted and this should thus also clear out any "previously opened windows" list.

If this doesn't fix the problem, do the following to reverse the above:

Delete any new preferences file that DPP may have re-created (again look for any file/folder with "DPP" in the name or something like "com.canon".
Double-click on the ZIP file you created in the earlier steps. This will re-create the original preferences.
You can now delete that ZIP file.

Perhaps the application itself is corrupt. So try uninstalling and re-installing the DPP software.

Beyond that, it could be a corrupt data file which could be just about anything. Sometimes that file would be somewhere in "Application Support" inside of that "Library" folder. Or could be corrupt files say in your Documents folder. So if you have backups made (that would be backing up at least the data files that the software uses) you could try restoring those files.

Hi there,

You will want to use the .dmg file, not the .zip file to complete the installation.

Thank you, the install is complete but I have duplicates of everything and am afraid to delete any since my edited work is all in there, so 😞

You may have multiple downloads, but I don't believe you can install multiple copies of DPP. To confirm go to the Applications folder.

Plus, the ZIP and .dmg items are not the actual application.You can delete any of them without a problem.

I use a free downloadable app called AppCleaner. It removes all residual files when you want to delete something. That sometimes then allows a clean install of an app.

It has always worked well fro me with no problems.
