newbie error? Can't get application id... this_path not defi


I’ve only just installed Devonthink, started putting all my files in and everything. I get options in Safari when I click on print - for example “save pdf to Devonthink2”. When I try to do this I get the message

I tried some other Devonthink related scripts and get the same error - or

Does anybody know how/where I do this?

Many thanks,


Which edition of DEVONthink did you install or are there multiple instances? Is it installed in /Applications?
