You know the page you are trying to open? If yes, then just use the Open URL script step. Point the URL to the file. And append the page number to the end of the URL. Something like this.
file:///Users/<userName>/Desktop/fileName.pdf#page=4 ( replace <userName> with the actual user name ).
Thank you for your reply.
Can we insert a variable for the page number?
Thanks for your help.
Your solution opens the pdf, but does not activate the requested page (with page number or variable). It seems that the problem comes from Acrobat Reader that does not allow it.
I am always taking if there is another solution ...
