Frequently Asked Questions
Why does Adobe Acrobat say 'Unable to connect to Dropbox' only on the first try?
This usually happens due to a timeout or a temporary session delay during the API handshake between Dropbox and Acrobat. By the second attempt, the background authentication process has successfully caught up, allowing the file to open.
Can I open Dropbox files in Adobe Acrobat without linking the accounts?
Yes, you can download the PDF file directly from Dropbox to your local hard drive first, and then double-click the local file to open it with Adobe Acrobat, bypassing the cloud integration entirely.
How do I check for updates in Adobe Acrobat?
Open Adobe Acrobat, click on the 'Help' menu at the top of the application window, and select 'Check for updates'. If an update is available, follow the on-screen instructions to download and install it.
