I believe the problems are happening after some Windows updates.
The problem starts with "Unable to Process the lock file" errors when printing journals and registers (trying to create PDF files for Paperless Office).
The solution I have been using is enabling the Sage 100 icon's "run as administrator" option.
The next problem occurs when the PDF file simply does not open after clicking print for a journal or register.
In fact, when trying to open any PDF file, the file simply does not open.
To fix this issue, I have uninstalled Adobe Reader DC and installed Adobe Reader X.
I am fairly sure this problem has been on Windows 10 computers, and I'm not sure if the issue will also happen on Windows 7 workstations.
Has anyone else seen these problems recently? If so, what are you doing to resolve these issues?
