Frequently Asked Questions
What does Error 16820 mean during a software download?
Error 16820 typically indicates a failure to communicate with the update server. In the context of Acrobat.com, it happens because the application's servers have been permanently retired and can no longer provide the mandatory version 2.3.0.0 update.
Can I still use the old Acrobat.com application to view files?
No, Adobe has officially discontinued the Acrobat.com service. You will be stuck in an update loop. You should access your documents using a modern, supported application like Acrobat Reader or WPS Office.
Are my PDF files lost if the application fails to update?
Your locally saved PDF files remain entirely intact and are not lost. You simply need to open them using an alternative PDF viewer by right-clicking the file and selecting a different application.
