I've had several people suddenly have a problem in Laserfiche where whenever they try to save a PDF they get a pop-up saying "There is a problem with Adobe Acrobat/Reader. If it is running, please exit and try again. (523:523). We've been trying a few different things but they seem to only work for a couple days and they get the error again. Anybody else have this problem, or know how to solve it? It seems to be a very sporadic problem that I can't pin down.
