I keep getting error codes 0xc0000022 and 0xc0000142 when opening pdf files. This started about two weeks ago about the same time I was having problems with Norton Security. The Norton Security issue has been fixed but not the pdf issue. I have tried a number of different things like uninstalling Acrobat DC and reinstalling several times, running the repair tool, etc. but still getting the error codes. Anyone have any suggestions?
