When I try to open a file downloaded, I keep getting an error message which says, unable to open file because it may be harmful or damaged. I don't know what is going on. I used to not have any problems opening downloaded files.
When you post a question you always need to tell the program you are using
There are MANY programs in a full subscription, plus other non-subscription programs
Please post the exact name of the Adobe program you use so a Moderator may move this message to that forum
