  • Fix a rare crash caused by the tray.
  • Fix an issue on Windows where the title for file system warnings was sometimes cut off.

Re: Stable Build 63.4.107

Explorer | Level 3

I've got 3 windows machines running the latest version of the windows 10 and I've installed 63.4.107. When I check after a few minutes, the dropbox version appears to have updated itself to 66.3.81 and I end up with the same error message: "There was an error opening this document. The file cannot be accessed by the system." The files that I'm trying to open are pdfs, word and excel docs that were uploaded by my home based Mac...

Can anyone tell me what I need to do to either keep the version 63.4.107 (assuming it fixes the failure to open the docs) or whether there's another recent build that handles this issue? Thanks much.

It sounds like you are automatically being updated to the latest beta build of the Dropbox desktop app. 

If you no longer wish to automatically have the beta build installed,  you will first need to follow these steps to verify that you have opted out of "Include me in early releases" option in your settings on This will ensure that the application does not automatically update to the beta build after you install the latest stable build:

  1. Log in to using your web browser.
  2. Click on you account picture/avatar at the top right corner of the page.
  3. Click on "Settings".
  4. From the "General" tab, scroll down to the section titled "Preferences" and uncheck the box next to "Include me in early releases" if it is checked.

Then, use the link for the latest Stable build to install the latest stable version of the Dropbox desktop application.

If you continue to see an issue with this stable version, please write in to support for assistance. 

Thank you!



What are stable and beta builds?

The stable builds are for the Desktop client, which is regularly updated with many improvements and fixes.

A beta build is an early release feature that is subject to these additional terms.
