How can I update my desktop app on Windows 11 to the latest app version?

amcoffice

I've recently had a lot of trouble with PDFs that are visible in iPhone app and on the website but are not viewable in Windows 11 File Explorer (just get Microsoft Edge home page or a file-not-found error). I've done an inordinate amount of research and troubleshooting. While there is no apparent syncing, security setting, or cache issue, I did discover that my destktop app is not updated to the current version (desktop app says version 266.4.3911, but the latest version is apparently 270.4.3246).

Why is my Dropbox iOS desktop app not updating automatically?

How can I get my desktop app to update to the newest version?

Thank you!

Thanks for posting on the Community today, @amcoffice.

You can try to manually update your desktop app to the latest stable app version via this page.

If you still can't see your files locally after this, feel free to share your app’s syncing status with me, and we’ll look into this further.

I’d also like you to check if the files you can’t see on the Dropbox app contain any of these characters in their filename.

Keep me in the loop for more updates.

Thank you for your prompt email.

I had already tried to update via the Dropbox web link without success. I tried again on page you provided and got the same error (see screenshot - Microsoft app already installed). Uninstalling Microsoft app and and reinstalling Dropbox desktop app from Dropbox page also did not work; only Dropbox app that I could get to install was the Microsoft app. Also, as noted in my original post, PDF issue is not consistent and does not this does not seem to be a sync or cache issue.

Why is Microsoft dekstop app not the most update? Or how can I update it?

Uninstalling and reinstalling Dropbox app (even the Microsoft one) was a HUGE pain and caused mayhem with my Word and Excel documents.

All help and guidance welcome. Thanks!

Based on the error on your screenshot, and what you also mention, it looks like you’re currently using the Dropbox app for Windows in S mode (Dropbox Lite). As mentioned in this Help Center article, this type of app doesn’t store files/folders on your device, but it works more like the Dropbox mobile app.

You said that you uninstalled the Dropbox app from the Microsoft Store, and then installed the Dropbox desktop app, but without success. Can you please clarify what happened exactly when you tried to do that? Did you follow these steps to switch out of S mode on your machine first?

Since I do not have the energy for a full response, so here's the long story short.

I finally got my Dropbox desktop app to update to 270.4.3246 version by opening the Microsoft Store library and getting Dropbox app it to restart and maually update. So easy that I'm not sure why I could not find that answer before I started an unnecessary uninstall and reinstall debacle yesterday - almost lost ALL of the Documents and Downloads that were on my laptop and then had to consult (and pay) an IT professional to save them.

Bottom line - Now that I finally figured out how to update Microsoft Dropbox app manually it appears that my Dropbox desktop app (whatever it is, Lite, S mode, etc.) is working like it was before I noticed the PDF and update issues. Probably just kicking this can down the road until I have another problem, but I'm good for now.
Thanks!

Hi @amcoffice, thanks for the update.

As you've noticed the Dropbox Lite/S Mode app is different from the full Dropbox desktop application, as the latter creates the Dropbox folder for you to directly sync your files.

Regarding the PDF issue, as you mentioned that it opens them in Edge, have you tried installing a PDF reader instead to see if those files can be viewed there instead of the browser?

amcoffice

Thank you for the reply. Whatever I have, it is now fully updated and seems to be working OK again (even for PDFs), so I'm going to leave well enough alone for now. Thanks again!
