CertFindCertificateInStore failed with: (-2146885628) Cannot find object or property.

For the record, this error still exists as of 2024-07. It is genuinely shameful that this has been kept for so long.

I was wondering what was crashing my PC, so I checked the Event Manager. Every single crash was preceded by 6 to 12 instances of error messages regarding DbxSvc, Error 281, CertFindCertificateInStore failed with: (-2146885628).

Having read the thread now, the solution seems simple: If this asks for a certificate that just isn't there, it should stop asking for it.

I find it funny that support claims that its fundamentally not a big problem, when my PC is crashed by this error about once per hour. Must be nice not having work on your PC thats not important enough to lose it.

Can you please fix it?

i see this several time every day with Windows 11

seeing this with Windows 11 now

4 years later and this is still happening. Recently my computer started freezing and I could not do anything except force shut down with the power button. I went into Event Viewer and saw multiple errors from 'DbxSvc' (-2146885628) Cannot find object or property.

I have lost unsaved work from this issue and it has risked corrupting my files from forcing the computer to shut down so I have completely uninstalled Dropbox from all of my devices and will be warning anyone I know who uses it until this is fixed. 

I did an Advance Reinstall.

Problem remains.

Same issue, looking at the event viewer gave me to same error. Doing a google search for it brought me to this thread. 

It's been some time since my original post, and I've learned a lot since then. The PC affected by the issue had an Intel 13th generation i9 processor, which is known to have instability issues that become more apparent as the processor ages. There's a wealth of information available on this problem, so I suggest doing a quick search to see if you might be affected.

I want to emphasize that this processor may or may not have been related to the crashes involving the Dropbox certificate store. Intel has provided several fixes for this issue, most of which involve updating the BIOS to better manage the processor environment. However, none of these fixes were 100% effective for me. I achieved the best results by using the Intel Extreme Tuning Utility to underclock the processor. Interestingly, the benchmark performance was actually better when the processor was underclocked.

In the end, I persuaded the PC manufacturer to replace the processor, and I haven't encountered any of these issues since the replacement.

Si le problème semble persister, c'est peut-être parce que le disfonctionnement de Dropbox serait une conséquence de la corruption de l'index de recherche Windows (qui peut d'ailleurs occasionner d'autres problèmes.

Voici la procédure recommandée, que j'ai appliquée, qui semble marcher !
