Have you talked to DTP Tool support? It's usually best to contact the developer to get help.
I have tried to contact them, but it's actually Adobe that doesn't recognise the plug-in. Would that still be a matter for them to deal with?
Have you heard of the program? Do you know if it legitimately works?
I am not familiar with the program but I don't usually use third-party plug-ins for InDesign. Yes, that is exactly the question you should ask the developer. Perhaps someone else is more familiar with it.
I actually wrote a review of it a few years ago, but I haven’t used it much since. I’m not even sure what version of InDesign I tested it with.
Have you looked at this page for a CC installer?
Thank you, I will take a look at this.
Otherwise would it be easier to compile a PDF package? Would that still allow the user to update numbers in the excel part of the package?
