How to open PDFs in the new window?

[michaelw45595349]

Could someone know how to make the first Adobe instance can just display one single document. Do not allow any other Adobe instance to attach to it ?  

For example if I open one adobe document it open one instance of Adobe.

But if I just double click on another Adobe file, it create just another tab in the first open adobe instance. I want it create another instance of Adobe. Use comman line /n can control the second open instance to open as a seperate instance, but can the first adobe instance to disallow the attachment for any other Adobe instance. Any Adobe call back function or command line could achive the goal for the first instsnce of Adobe ? 

Thanks.

Hi MicahelW,

Thanks for reaching out, As described above, you want to open PDf files in the new window, correct?

Please try the following preference settings and see if that works for you

Go to Edit (Windows), Adobe Acrobat /reader DC (Mac) > Preferences > General > Uncheck , open documents as new tabs in the same window > Click OK >  Restart the application.

Let us know how it goes

Regards

Amal

Hi Amal: Your answer is excellent, but my question is little more deeper on the developer side. I would like to know if the already opened the Adobe instance can refuse to allow other adobe instance to attach to it. We have a program that can lunch instance of Adobe, but do not want any other instance of Adobe to attach to it if the current instance did not closed yet, since we have code to monitor the current instance to close then we perform some action on the Adobe file, in the usual case we ahve to close all the tab of Adobe in order to perform our action. Just wondering if there any call back function that we can use or some command line option to make this Adobe instance do not allow another adobe instance to attached to it. I know another way around works if we use command line switch \n, this allow to open seperate Adobe instance even if there is already adobe instance exist, do not attach to the existing adobe instance. Hope you understand my situation and issue. Thanks.
