Once I clicked download pdf I want to do some actions in my pdf so I created a new business object for the PDF. I am not able to attach the pdf to the object. The pdf will already be running. I can not use the window title because it will always be a different name, when I use the process name I still get the error message 'target application could not be identified'. Thanks for the tips.

Sometimes the PDF can appear in a nested browser process and sometimes it can come about in it's own process Fri, 24 Feb 2017 15:21:00 GMT https://community.blueprism.com/t5/Product-Forum/Attach-PDF-Object/m-p/80494#M32210 DexterWhelan1 2017-02-24T15:21:00Z https://community.blueprism.com/t5/Product-Forum/Attach-PDF-Object/m-p/80495#M32211 You could: Use a wildcard in the window title - so it is something like ""* - Adobe Reader*"" or You could leave the window title blank and just attach to the adobe reader process, first making sure that there is no readers already open before you open it.
