Digital Photo Professional 4 Non-responsive Following File Save

[jazzone]

I've been using DPP4 since its introduction on my Windows 7 desktop without incident. I just upgraded to a new computer with Windows 10, more RAM (16 GB), and faster CPU (i7-8700). I now find that DPP (4.7) hangs for about 30 seconds following a file save.The strange thing is that DPP (and only DPP) becomes temporarily non-responsive following ANY file save, even a small Notepad text file. Watching Windows Task Manager, I see that the CPU utilization jumps to about 12% following a file save for about 30 seconds, but only when DPP is open. Any idea what's causing this and how to fix it?

Came on here following suffering the same issue which was driving me nuts.

Thanks for the suggestion of the solution

I've found a similar but much easier workaround which is to simply right-click on the DPP4 Shortcut and select 'run as Administrator' ..no more slow downs / hangs

The fundamental issue seems to be with the permissions being assigned to a user are 'Special' and not 'Full Control'

I've yet to tinker with these

Replacing my photo HDD with an SSD made a great deal of difference.  MUCH better.

I can not get back to v3, CR3 have to using on V4.1 or new, there is the point of.

you have to check off the ram using, then you will be shocked more. My computer is i9700+32 DDR4+SAMSUNG 980PROX2 on RAID0+1080GTX+Toshiba 4T HDD. , after the files had been saved and the program killed 1.2GB RAM.

I have 1DX mark ll, so I have to update my DPP to the newest, but the problem is same as most of the people, when I save the files, then the DPP has been freeze. I have a clean Windows and buy a new computer but the problem is the same. 

my computer: i9700/ 32G DDR4/ Samsung EVO980 Pro SSD on Raid/ Toshiba 4T Sata hard Disk X4/

I talk to the canon service center on HK, on JA, on TW, on CHT. from V4.10 to newest, but it has been nothing to change. Do we need to change the camera company or not?

I am using the current version of DPP with a 1DX and 1DX 2 and it is working well with no freeze on file conversion/saving.  The only time it is annoyingly slow is when applying digital lens optimizer with a file that was shot at high ISO and is undergoing significant noise reduction and at times it will take up to 25 seconds to complete processing to display the image HOWEVER file conversion/save is still fast under these conditions.

You should have plenty of processing power and memory with that setup and I suspect it is a Windows 10 issue related to a driver for one of your devices.  I lost count long ago of how much time I have spent dealing with Windows 10 issues on several different high end machines, unlike its predecessors it is far less robust over a wide range of hardware.  Most of my use of DPP is on a HP Z-820 with twin Xeon processors and 256 GB of memory (128 gigs per CPU) but I also use it occasionally with a HP Zbook that uses a 4 core processor and 32 gb of memory with no freezing issues.  Some of the earlier versions of DPP did have a memory leak problem that slowed them down even though they only used a small percentage of system memory but I haven't run into that with the current version and after some all day sports shooting I have worked on directories with over 1,000 files from the 1DX and 1DX 2 for several hours with no slowdown issues.

I did have to jump through multiple hoops with both PCs during recent major updates to Win 10.

If you haven't already done so, completely uninstall DPP using the Windows control center and then install it again.  Take a look using task manager when it is freezing during save to see what is going on with CPU and storage loading, you may have a virus or malware program interacting with DPP.  The malware protection that comes with Win 10 is a major resource hog.

I think that was when we are up to win10 and work for a raid system then DPP should be freezing. I have 4 computer system, Win10 are all of them, but it is not on Raid being only one, that one would be no problem of any problems of DPP3 to DPP4. Which the new system is running with m.2 Nvme Raid and another computer system was E3 Xeon and just upgrade to PCI-E SSD Raid, before it has the basic a hard drive system with two years ago then all of the problems are coming for DPP.

So that I think DPP has not to support any kind of new hard driver, and I also talk with Microsoft engineers and they are proving the Canon Dpp4 is not support the Win10 system.

Hi All,

This has been bugging me too of late, ever since I brought the 90D a few weeks ago and upgraded my version of DPP, this solution obviously might not work for all but it certainly sorted out my latency save issue amongst a few other slight performance issues on Windows 10!

The Culprit and Solution for me was that I have a second Computer on my network that I only turn on when I need to, (say for backup purposes) and I never disconnect the two attached drives from within Windows Explorer on my Master Computer, I always have these drives showing albeit they are "disconected", and obviously get a warning that Windows "Could Not Reconnect All Network Drives" everytime I reboot/login if the said Computer is not turned on. Once I actually Disconnected these drives from within Explorer my Issue with DPP4's latency dissapeared, therefore my conclusion is that DPP4 is periodically trying to connect to these drives when an action is performed.

Hope this helps someone as I couldn't find any resolution that worked for me and just by chance thought to try this after being bugged for a few weeks!

Cheers

Thank you Nickerzzzzz - I think this may be my solution as well. I have a NAS device that Windows 10 hasn't been able to connect to since last week and for days I have been having issues with DPP Not Responding. Even talking with Canon and trying additional things including setting up a 2nd profile on my computer we could not ID what the issue was. I knew it was Explorer related, but couldn't figure out quite what. And simply deleting that NAS works. I don't need it on my network as I migrated the files on it to my new NAS, so fingers crossed, problem is forever resolved. 🤗

Yikes, spoke too fast. As soon as I tried to Register settings, thus saving them, the application went back to Not Responding. So I guess I will be running DPP as a different user. So, know I have to figure out how to see, access, and save the files on my primary account when I use the app as a different user.

SMH - this is extremely frustrating.

Figured out how to give permissions to my 2nd user to the folder. Weird way to run DPP, but will see if this works

DPP has been a mess for years now.  I went to all SSD processing, a good cpu, and plenty of RAM and that means it only stalls once in a while.  I finally bought DX0 Photolab and all my RAW processing goes smooth as silk.

I stongly suggest dumping DPP for something better (Lightroom, DX0, or ?)
