Another non-starter

Resolve 18.6.4 which was working happily on my system last week has decided not to start. Hangs at the "Loading Project Settings".
I have tried:
1. Renaming C:\users\<name>\AppData\Roaming\Blackmagic Design\DaVinci Resolve to something else so it recerates the folder. It started up with "new user" type Wizard then disappered. Upon a reboot I get the hanging at "Loading Project Settings"
2. Complete uninstallation (of Resolve and Resolve Control Panel) then a reboot and reinstall of just Resolve. Same result.
3. Deleting config.data and config.dat from within ...\Preferences. Same result.

In all cases - and something I haven't seen reported by others - Windows refuses to restart after a failed attemot to run Resolve. (If I don't attempt to run resolve, WIndows restarts perfectly.

Something that happens is although you force quit the program, it's still running in the background. Go down farther in the Task Manager and you'll see that it's still running. Kill that one too and you'll truly be able to do what you want after.
I've got nothing about the rest but if you search the forum, there's a thread about deleting something from Regedit as well to truly kill any semblance of the previous install. I think it was made by Dwayne to instruct about a total reinstall?

Good luck and if you can't figure it out, Post logs and system data.

Hi Ben

Would you have any specific tools/actions/sequence of steps that will result in needing to force quit Resolve?

The persistent background process isn't something we have seen reports of in a while, and if it is still a thing, we'd like to narrow it down.

Thanks

It was especially bad when I was using the MediaIn node set to Background to create a picture in picture window of the timeline. At that point the timeline consisted of a story board sequence of pngs. I'd then put a Fusion Comp on the next layer and use it to start blocking out the 3d scene to match the boards. I'd use a MediaIn in node at the end of my flow transformed into a small window tucked up in the corner while working on things.

The other thing that would cause it was once I had the shot blocked out, which involved a few FBX models imported into the scene, going back out to the main timeline. I'd then start to stall out and Resolve would be unresponsive. At that point I would make a log package and forced quit. After that I would wait a while and forced quit again. If I did not, it would slowly eat my RAM 10Mb at a time till the machine crashes. Which would take a while with 128 Gb.

Then if go back into Resolve and find multiple copies of the FBX files in a random folder. One for each of the Fusion comps that the same model used for different shots.

The error logs always reported the same thing. A dirty api call over and over again. And something about Jenkin's users space?

In both these cases, it didn't start presenting until I had at least six or seven Fusion comps laid out. It didn't happen with just one or two. I also had the dirty api hang happen today while using the MediaIn set to Background so I could make a set of badges overlaid on top of some spots. Just simple pngs of software logos made small and fade up. I was working on my Mac and just had to hit the force quit button a few times for it to stick. If I didn't do it a couple of times it would not quit.

When this happens to me and the crash dialog appears (which it typically does when force quit is selected), I always try to add a description of what I was doing and the general setup of my project. Hopefully those are read by someone at BMD (even a bot?). Happened to me a few times the other day when I was taking alpha from Fusion as second input to the color page and doing some magic mask compositing in the color page. Couldn't reproduce it now.

With regard to my original post, a complete uninstall (removing the three \Blackmagic Design\ folders in addition to unistalling the Apps, appears to have fixed this. The registry entry refereed to in Dwain's post did not exist (after the unistall, didn't look before).

For bug tracking...
Here's the tread I submitted with the Logs.

I also have a similar problem. I installed davinci resolve(free version) on my new PC and it doesn't start. It's the only software that gave me problems. can you help me?
A thousand thanks

Submit the logs as described in the FAQ which is stickied at the top of the forum.
Dwaine will surely chime in with the answer.

I've had some occurrences with older versions where it looked like Resolve wouldn't start, but if I left it for long enough (like 10 or 15 minutes) it would eventually come up. Once it got past that hurdle, it would come up normally in subsequent starts.

@Filippo:

In a File Explorer window, go to:

C:\Program Files\Blackmagic Design\DaVinci Resolve

and run CaptureLogs

This will place a Resolve log file named similar to this on your Windows Desktop: DaVinci-Resolve-logs-20181228_140434.zip (You may not see the .zip extension if your system is set to hide known extensions).

Then open the Windows System Information app and do a File - Save (Not a File Export), which will generate a .NFO file.

Place both those files on a file sharing site and provide links to the files here. Make sure the links don't require access credentials.

If you are a new Forum user, you may not be allowed to post URLs. If this happens, just put a space near the front of the URL, so the system doesn't think it's a URL.

Good morning, I hope I did well! I bought a new PC, I installed all the updated drivers, I downloaded and installed the free version of Davinci Resolve, but it doesn't start, not even the initial screen starts.
Can you help me?

You didn't provide the requested .NFO file...

[Dwaine Maggart]

Need the .NFO file as well.

Need the .NFO file as well.

I am sorry
I hope it's okay now
thanks for help

Your Resolve config file is definitely corrupt. But there are no helpful Resolve logs to tell what your user path is.

My best guess is to have you do this:

The following process will MOVE your Resolve preferences files to a backup location. This will force Resolve to create a new set of default preferences files when it launches. If this solves the launch issue, that would imply there was some corrupt preferences related file causing the startup issue.

Open File Explorer Options, and on the View tab, enable "Show hidden files, folders and drives".

Also unselect "Hide extensions for known file types".

Then in File Explorer, navigate to this folder:

C:\Users\7950x\AppData\Roaming\Blackmagic Design\DaVinci Resolve

Rename the Preferences folder to Preferences.old

Now see if Resolve will start.

If it does, it will have all the Resolve preferences set to default values.

And if you had any other Resolve Preferences items modified from their default values, you'll need to modify those again as desired.

If Resolve still doesn't start, send a new Resolve log file.

By corrupt Dwaine do you mean zero-length or that it actually contains bad data?

[Dwaine Maggart]

Full of NULs.

bad_config.png (30.74 KiB) Viewed 330 times

Interesting. Ever seen that before?

[Dwaine Maggart]

Occasionally. If you look at such a file in most text editors, it will just appear to be blank.

WAu!!!! it's work!!!!
