Dorico 4 Pro not starting on Windows 10 with Blackmagic DeckLink Recorder 4K video card installed

I installed Process Explorer. Dorico4.exe is showing while the splash screen is visible. Then the splash screen disappears and the process is gone. VSTAudioEngine is still running after that.

I was able to catch some screenshots:

Now it has started once again - totally random.
application.zip (1.7 KB)

I used Hilfe>Diagnosebericht erstellen to create a file on my desktop (Dorico Diagnostics.zip) but it is too big to upload.

Here is one CrashDump from that file
Dorico4.exe.1772.zip (1.2 MB)

Aha! :smiley: There we go, that’s what I wanted, an actual crash dump file.
Excellent, because that shows that Dorico crashes in DeckLinkAPI64.dll.
Do you have any idea what that might be and where it comes from?

Probably related to my Blackmagic DeckLink Video Cards that are installed.

See my post #7: Dorico 4 Pro fails to start on Windows 10 - #7 by rick2703

When I deactivate my
Blackmagic Mini Recorder 4K Video Card
Dorico 4 is starting fine.

So we found the problem, but what might be the solution? - I need this card.
The drivers of these DeckLink cards are up to date.

Yeah, found the culprit, that’s good, but to be honest, now I’m out of steam, someone else has to take over. @dspreadbury , someone from the London team might have an idea?

Do you need the card when you use Dorico 3.5? or only when you capture or play video with other programs?

Do I understand correctly that the BlackMagic card doesn’t have any video outputs of its own, and is purely used for capturing video?

@dspreadbury, that‘s correct. Only Inputs.

It’s a bit of a mystery, then. I will certainly ask my more learned colleagues if they have any ideas about how to proceed. However, it now being the weekend, I’m sorry to say that I very likely won’t have any further suggestions until into next week.

@rick2703 , one more thing to better understand the whole thing. Can you please have a look on your computer where that DeckLinkAPI64.dll resides on your computer so that we can better understand from where and why Dorico loads in that library? Thanks

@dspreadbury , no problem at all. Thanks for your efforts and have a nice weekend.

@Ulf , you too have a nice weekend. I will provide the information until monday.

Hello,
Maybe irrelevant, but I had a pci card which caused a conflict with a software, so that in the end I had to create a batch on the desktop to put on or off this card before using and after its use the spitting program!
So if it can help and be used as a workaround for the moment: here are some links to guide you:

Thank you @Dup, I actually thought about something like this and will give it a try this weekend. :+1:

My colleague Paul did come back to me before he clocked off for the weekend and requests that you run the attached script capture_dorico_crash.bat in a Windows Command Prompt window. Hopefully this will output a dump file to Documents/Crashes. The resulting dump file may well be too big to attach here even if you zip it up (4MB is the file size limit), so if that’s the case, if you could send it to me by email at d dot spreadbury at steinberg dot de, that would be great.

When you run the script, it may ask you to install a Microsoft/Sysinternals utility called procdump. Once it finds procdump as expected, it’ll then ask you to run Dorico. Assuming Dorico crashes as expected, you’ll find the dump file in Documents\Crashes.

Hello @dspreadbury , I have sent you the created crash dumps by email.

@Ulf : the DeckLink Audio64.dll resides in “C:\Program Files\Blackmagic Design\Desktop Video
