DPP4 won't open on Windows 10

whyfret — Thu, 25 Nov 2021 13:21:34 GMT

I have installed this program on my new laptop and it will not open. I have been on the phone with a Canon rep and he was unable to help me. The program picture will pop up breifly (black box identifying the name of the program) but then closes. I use Windows 10. I have deleted all antiviral programs. I can open it on my old laptop. Any ideas of what the problem may be?

Greetings,

We will need more information to try and assist.

Please provide your laptops hardware specs?

Windows 10 - Feature and build # is?

Is your user an administrator?

What version of DPP did you install? (4.15.20 is current as of this post)

Open the System Event Viewer, review sections "Applications" and "System"

See if any infomation about the program (correlates) to when the software fails to open or run.

We will await your reply.

Thank you for your response.. please understand my technical skills are limited. I do not know where to locate the system event viewer. There is a program called Tram Reviewer where I can send you permission to access my computer for a 1 x only event. Is this something you would consider?

Windows 10 Pro 21H1 OS build 19043.1348
DDP 4.15.20
I would guess I am the administrator

Ok. I found the event viewer. I see where a it lists the problem with the application. Do not under it though. I have Uninstaller and reinstalled with Canon tech rep and it still did not work

Greetings,

Good progress.

Is your system intel or AMD based - CPU / Processor?

If your account is the only one that exists on the machine., it would have admin level permissions by default.

Error listed / Event Viewer. If you double click on the entry, a window will open with the copy option.

Now paste that for us to review.

Team Viewer is a remote control / access software which can be iused for remote support. I don't think this will be neccessary.

Greetings,

You are very close.

Double click on one of the Application error entries. That will open the dialog I was referecing above. Does it indicate a problem with DPP? Confirm that for me.

Next step.

Start menu type cmd

This time however, select Run As Administrator

At the prompt type >sfc /scannow

(note there is a space between sfc and the forward slash)

Press enter

Let this run. It should complete in under 3 min.

Let me know the result.

"Windows did not detect any integrity violations"

"Windows found corrupt files and repaired them successfully"

Windows found corrupt files and could not repair them"

If corrupt files were found and repaired succesfully, close the command prompt window. Restart your system and test opening DPP for me.

Well a giant hug and thank you for all the time and energy you have so generously given me. I was hoping to avoid taking it to a computer repair store but it looks like that is what it may take.
I hope you had a wonderful Thanksgiving and I was wondering if you would share your address so I can send a small gesture of thanks your way.

Greetings,

No gesture is necessary . We're all here to help each other.

You actually accomplished quite a bit. Based on the number of errors in your event viewer, I think its safe to say that a driver, software or application DPP depends on is faulty, missing or corrupt. This is likely why it won't run.

Did you ever review one of the Application error entries in the Event Viewer to determne if it provided insight or cause for the DPP failure? When you open that list, double click on the line item and review the details.

I don't think a visit to a repair shop is needed as I believe the problem is related to software and can likely be figured out.

I know that many folks do not recommend or feel that registry cleaners are necessary, but I had a problem with DPP functioning (not the same as you are describing) and when I used the free CCleaner app to clean my registry the problem went away.

It also resolved a problem I had with updating the Nik Collection.
