Vijeo Designer - Multiple Adobe processes when opening PDF

[DelilleC]

Hi,

we have an HMI project running with Vijeo Designer Runtime on an iPC that displays PDF documents once at the time.

For every PDF to display, a specific Adobe Acrobat Reader DC process is created, resulting in multiple Adobe processes running.

At some point, Adobe crashes with this error popup: "There is a problem with Adobe Acrobat/Reader. If it is running, please exit and try again. (1008:1008)"

Is the multiple processes creation a normal behavior, or is there a good practice regarding PDF documents display with a specific "Close document" action to perform?

Thanks for support
