Thanks great feedback - yeah the prompt is a little/very unclear... And probably completely unnecessary, I think it should just save the new product version if it looks valid since the user just explicitly edited it - I will be changing that.

I am also going to add Netsparkle (or other updater) to the application to allow proper automatic updating of the binaries. That will make it very clear when there is a new version of the license manager available and what has been updated.

I've got some feedback.
...
"New Version detected, do you want to save it?"
...
I played around with the Manager some more and found out the dialog prompt in the first place was talking about the Product Version I entered in. Perhaps that dialog could be made clearer by saying something like "You added a new Product Version. Would you like to save these changes?"

I have actually been looking at a solution for locking Excel files which would be possible to do with PDFs too, unfortunately Adobe require a $50,000 per year :tellme: DRM agreement if you add plugins to Adobe reader which restrict access to or encrypt PDFs... So I wont be implementing that anytime soon!

It would be of course be possible to implement the license as an executable file which then opened an embedded PDF - unfortunately you would have to open the pdf through the launcher each time to retain any kind of security. But it should work.

I will create a proof of concept to see what is possible!

@josant - Very nice product.

I was wondering if you ever considered combining the validator part with a wrapper for a document file.

Ideally, the manager could be a simple utility to drop something like a PDF into it and create a one off license. Then the PDF could be combined with a locked launcher. The document could then only be unlocked and launched the first time by the buyer using the provided license key.

After that however, it would just display a splash screen with an "Exclusively licensed to: {name} call-out which you'd need to click through every time you opened the actual document.

Might be nice too if the file required a reapplication of its license key if it ever got transferred to a different PC.

That could be a real boon to people who produce and sell licensed instructional materials. Would go a long way towards cutting down on casual license violations.
