I'm currently running Windows 10 Version 1909. Each month after Windows Updates, most of my computers have an issue where Adobe DC Reader will not open until the PC is rebooted second time. I've verified that Adobe is on the latest version. At first I thought this might be an issue with my anti-virus (FortiClient) so I uninstalled and reinstalled the program on all of my PC's. This seems to have fixed it on many of them except for a few. Is there something I need to look at as far as registry settings? Any ideas on what may be causing this?
