Quite Imposing Plus - Protected Mode on Windows
For Windows users, Acrobat Pro DC and Acrobat Pro 2020 added a new feature called Protected Mode. This is designed to protect files from being read by future hackers who find a way to attack through a downloaded PDF. The idea is called “sandboxing” and is now widely used in many apps. Unfortunately, the effect of this feature was to block many plug-ins, because they need to read files!However, Quite Imposing Plus 5.2 has full support for protected mode in Windows. We do not now recommend turning off protected mode. You will receive a prompt the first time you read a file in each run of Acrobat, if it is used eg for a background page or data source.
