Dropbox desktop app causes an "Event 3033" at every startup on my Windows computer
I see Microsoft Windows Event 3033 created at every startup of Dropbox version 224.4.4811.
Code Integrity determined that a process
(\Device\HarddiskVolume4\Program Files (x86)\Dropbox\Client\Dropbox.exe)
attempted to load
\Device\HarddiskVolume4\Program Files (x86)\Dropbox\Client\224.4.4811\vulkan-1.dll
that did not meet the Microsoft signing level requirements.
Please explain what the vukan-1.dll is, and ask your developers why it is not meeting the Microsoft Signing level requirements.
Hope you don’t mind, if I jump in here, td47. I checked this with our team in the meantime, and they also confirmed that this is a third-party issue, and not one directly related to Dropbox.
What you can try instead is to download the Dropbox app via the Microsoft Store, as it shouldn’t contain vulkan-1.dll.

Hello DBoxTips thanks for your useful input.I have got this on Windows 11 24H2, and Windows 10 22H2 (Build 29045.5854).
I have been looking at the Certificate side of things, and it might be because the PP & PPL (Protected Processes) checking within the Code Integrity checks in the Windows OS process Loader.
Check out:
Forums.Malwarebytes.com topic 325667 (sorry cannot seem to publish the actual link)!
It looks like most stuff needs Authenticode and WQHL signing if they request low level (i.e. Kernel) access to other drivers.
Vulkan is the cross-platform API library used by Electron, the user interface framework that Dropbox uses for their desktop client.
I installed Dropbox 224.4.4811 and could confirm that the digital signature is there for the vulkan-1.dll file.
What version of Windows are you running? I will try to use that to reproduce what you're seeing.
Update: managed to reproduce this on Windows 11. I will look into it and follow-up here.Hope this helps,

P.S. I am a volunteer on the Dropbox forums, freely and happily sharing know-how with other users, not affiliated with Dropbox in any way.This is NOTHING to do with anti-virus options, it is the INBUILT Windows Code Integrity checking of executables, done by the in-built security mechanisms of the operating system.
These can be seen in the Event Log at:
Applications and Services Logs -> Microsoft -> Windows -> Code Integrity ->Operational Log

Thanks for bringing this to our attention, td47.
This is a pretty strange issue you seem to be having.
Do you have any security apps like an antivirus, firewall or VPN for example? Can you ensure they're configured to allow Dropbox processes (Dropbox, Dropbox.exe, DropboxUpdate.exe)?
Also, what is the Dropbox app's sync status? You can see that by hovering over the Dropbox icon in your system tray.
Let me know and we'll go from there.
