How do I remove the DEMO watermark that qiqqa put on all my pdfs without my knowledge??

Please help! @GerHobbelt @jimmejardine

That is very weird.

Have you installed qiqqa after downloading it from the github releases web pages or did you fetch the software somewhere else?

Best regards,

@GerHobbelt I downloaded it from here, I think: http://www.qiqqa.com/Download

Ok, that removes at least one suspicion of mine. That's the site for commercial Qiqqa.

So the plot thickens... we'll have to check a few more things, because I don't have any idea how this can come from inside Qiqqa.

Qiqqa still uses a few commercial libraries, one of which is used to render PDF pages on screen, but I've never observed this behaviour before from that library. So question number 1:

• where exactly do you observe these 'Demo' overlays? Is that in the Qiqqa PDF viewer itself, i.e. in the application itself when you look at a PDF? Or does this happen elsewhere? A screenshot helps to diagnose this, e.g.:

Additionally, it might be handy to upgrade to the open source version of Qiqqa. For this, you can see here: https://github.com/jimmejardine/qiqqa-open-source/blob/master/README.md and for the moment I'ld advise to fetch the latest test/pre-release at https://github.com/GerHobbelt/qiqqa-open-source/releases/tag/v83.0.7656.6401.

Would be good to scan through https://github.com/jimmejardine/qiqqa-open-source/blob/master/docs-src/FAQ/Installing%20Qiqqa%20-%20Updating%20Qiqqa.md before you do this as several questions folks have about this are answered there. (By the way: no need to uninstall the previous Qiqqa version: those installers simply replace the current install and your data is kept intact.)

Please see if this open source release (which still uses the same commercial libraries) gives the same results.

Let me know how it goes, so we can diagnose this conundrum further and get you going,

Cheers, Ger

BTW: another thing to check, iff you're a bit tech savvy with computer internals 😉 , is to have a quick peek at the PDF files themselves: Qiqqa stores your PDFs in a documents directory tree inside your library folder, using content hashes for the names, so expect "cryptic" names like, for example, 60835FB1D237D8F3ED73653CC9F935FDD7FA16B1.pdf. (Qiqqa has a small database in your library where it stores the metadata of these PDFs, such as author, title, etc.)

Anyway, open one or a couple (we are just quick-sampling here!) PDFs in a PDF reader application, e.g. FoxIt Reader or Adobe Acrobat, and check if the overlay occurs then -- this way we can ascertain that the problem is in or very close to Qiqqa and not some other (software) component in your machine.

To locate your personal libraries, check https://github.com/jimmejardine/qiqqa-open-source/blob/master/docs-src/FAQ/How%20to%20locate%20your%20Qiqqa%20Base%20Directory.md for guidance.

Here's a quick screenshot of one of such PDF storage directories on my own machine, so you get a bit of an idea what to expect there:

@IngaJulia : any luck so far?

[GerHobbelt]

@IngaJulia : ping? Have you looked at my feedback about your Qiqqa install and items to investigate, dated June/July? (See above in github issue tracker) Thanks! 👍
