Dropbox App not starting - Windows 11

[LangstonS]

I downloaded and installed Dropbox, but it does not give me an option to Sign in. Just the starting screen pops up. 

I have done the following rebooting, and checking the ISP and firewall allows Dropbox, uninstall and reinstall & advanced reinstall. 

I am now out of options, this used to work on the same PC before, but it looks like a Dropbox update has broken this.

To add, it is very frustrating that we cannot contact support directly, I am Tech support for a school and the issue is affecting our head teacher's device, who has a paid plan.

Hi @LangstonS, thanks for bringing this to our attention.

If the sign in screen isn't appearing, are you certain that there isn't any proxy, VPN, firewall, security software, or even ISP/router settings that could be restricting traffic to the following Dropbox domains?

This will help me to assist further!

Hi Jay,

We are certain there isn't any block as another user is working fine and we can ping the IP for Dropbox.

All URLs are in our firewall as allowed.

Thank you

To add I am now seeing an error in event viewer: 

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

A little unsure what this means.

Thank you

Could you try another advanced reinstallation again for the desktop app, given this recent error?

[LangstonS]

Hi Jay,

Just gave this a go, still no luck 🤷‍

Also seeing the same error in event viewer.

Thanks

In that case, we'll need to have the user contact us directly from their paid account, in order to look into the account and device via our systems.

Hi Jay,

I have tried to contact both my account and the paid account, and both times I was told to use the community.

My PC is also having the same issue.

When is the next update for the Dropbox app?

Thank you

Shaun

you can check for new updates to the Dropbox desktop application from this page. 

Provided you're logged into the paid account, you'll be able to access the support page to email or chat to them directly.
