TeX Live is running on a Windows 10 PC.
I have installed the
psv package into the TeX Live by means of the Manager.
psv complains when run. The error message mentions "display device" and I do not understand what is meant.
Hopefully someone can find where I do wrong.
psv opens a window. It shows:

Added a few hours later:
More searches on the web showed me a solution out of the problem with psv:
It has been used to display rulers and grids. These are available in the Acrobat through
View Show/Hide Rulers&Grid
