Another DPP4 crashing in seconds after startup

EricL — Tue, 01 Apr 2025 22:18:57 GMT

I installed (and re-installed) the most recent DPP4 version to be used with my R10. Windows 11 incl. latest updates.
DPP almost immediately disappears while pointing to my download folder. From other posts, I found that the trouble may be caused by a file in the folder. I moved the whole download folder to another folder temp-download.
DPP4 stayed alive until I told it to look at the folder temp-download.
And yes, being a member of a museum crew, the jpg and other graphics files in my directories may have been edited with a large set of other tools.

From various bulletin boards, I noticed that this error has existed for over four years. Why was the DPP software not repaired during that period? Anoying for software called "professional". Any solution which does not require moving files around across temporary directories?

You should configure DPP4 to look at an empty folder on startup. It seems to use the default folder for Windows Media Player as a startup folder following a fresh install.

Again. Change the DPP startup folder to be an empty folder.

Dear Waddizzle, Your suggestion to keep DPP up and running some seconds longer is OK. However, when I try to select the photos/jpg in the "old" directory, it immediately crashes. Therefore it is just a temporary fix which does not solve the real problem.

I think DPP is intended for editing Canon created files.

“ However, when I try to select the photos/jpg in the "old" directory, it immediately crashes. “

How many files are in the old folder? DPP does not keep track of a file catalog. Every time it starts up it will survey the startup folder looking for image files. It builds up a file “catalog” based upon what it finds.

The search for media files can be time consuming if the contains a large number of files, including sub-folders. A lengthy search and scan can give the impression that the program has hung or crashed. I think it builds a preview of every valid image file it finds.

I suggest using a “working” folder, not the an entire library of image files. As John noted, there could be limitations on file types that it or will read that I am not aware of.

There have been reports that files edited by GIMP will generate errors and freezes in DPP4. There may be others as well. Your recommendation to open in an empty or small population folder is right on.

Yes, but if other files exist in the same directory, decent software could neglect other files and should not crash.
[your argumentation: it is perfectly allowed that Microsoft's Windows crashes when Adobe creates a pdf in a documents folder... ]

I don’t think it’s crashing. I think it is building a preview of every media file it finds.

I agree. Files that it “should” recognize (like TIFFs from GIMP) but doesn’t just show up a question mark. If the OP does some forum searching he can learn that. I have observed that a folder that takes a long time to open the first is much quicker the second time; most likely because, as you say, the previews have been generated.

I define a crash as: "the task/executable has vanished from the task list". No complaint about a possible slowness.

How can I configure DPP4 to look at an empty folder on startup?

Re: Another DPP4 crashing in seconds after startup

found it (chatgpt):

4. Verwijder voorkeursbestanden
- Ga naar: C:\Users\[jouw gebruikersnaam]\AppData\Local\Canon_Inc\DPP
- Verwijder die map (Canon maakt nieuwe bij herstart).
- AppData is verborgen; schakel “verborgen bestanden weergeven” in via Verkenner.

thnx for your quick response!
problem was I couldn't get there :). First I had to remove the folder in the Appdata folder (C:\Users\[jouw gebruikersnaam]\AppData\Local\Canon_Inc\DPP).
Good to know where to change the start up folder, thnx!
