3.5.2 here.
The solution suggested above should work for you too.
It, did! Thank you very much. I couldn’t post as I was new to the forum!
Excellent work Damon (for RPD)
Same issue here (Ubuntu 16.04, python3 3.5.2), the solution worked (downgrade PyQt5 to 5.10).
How lame of PyQt though… It’s generally a bad thing to keep out-of-date packages on a system.
Especially because it makes impossible in the end to track what is what…
Thanks for fix, had already spent too much time fooling with dependencies as hints found on internet related to same problem in other software !
After being stuck with a buggy version 0.4.1 in Elementary OS, I can now happily test this great version

I have released a new version, 0.9.10, which contains the fix for the bug encountered here, and several other fixes too.
Thanks for the new release. It’s cool.
Although, it’s not actually ‘fixing’ the issue with PyQt5, but it just forces a downgrade of PyQt5 to the exact version needed while installing RapidPhotoDownloader.
If you upgrade again PyQt5 to the latest stable version, RapidPhotoDownloader does not work any more.
I’ll feel this as concluded when everything will work without version cherry-picking 
I may be too religious, but an installer that downgrades lib packages does not make me feel fully at ease.
I’m still a great fan of this software, though.
I don’t think we’d have working systems if we didn’t version pick
We should get RPD in to an AppImage, flatpak, or snap, I think that’d help ease the pain!
I beg to differ… let’s not mix up version release with what I called version ‘cherry-picking’… Once a version is released and integrated, a ‘manual’ way back is usually an extreme measure (and not safe, in general).
As for your last point… I couldn’t agree more. An AppImage would be perfect, for exemple. Everything self-contained, whatever version of the libs that is needed wouldn’t affect the system software management.
Released and integrated into what, exactly? RPD runs on many many distros from Debian stable to Arch. “Released and integrated” means very different things in Debian stable and in Arch. You either use the older distro packed version, as in Debian, or you get components that go too far ahead and break. You’re hitting on one of the fundamental problems* about distro packing.
- means you have issues with your distro’s packaged version
This may easily become a very long discussion, potentially off-topic, I guess 
My point is just that this is the only software currently sitting in my computer that needs to ‘break’ some part of the software management of the system (in this case pip).
I have many other pieces of software (such as digikam) that need specific release or flavour of libs, not just one recent enough version, but they do not need all the system to be affected by their need (e.g. by running as an AppImage package).
I’m still talking about the ideal situation in which the requirements are defined as >=ver and not as ==ver.
And yes, I admit I’m quite pedantic… 
Rapid Photo Downloader cannot run without PyQt5 or Python (and many other dependencies). For now, PyQt5.11 does not run on Python 3.5.2. Period. For now, no program that uses PyQt 5.11 will work on Python 3.5.2.
Pip is not “broken” when it is used to install specific versions of a software library. That’s what it is meant to do. By default it will install the latest version, but that’s just a default. Sometimes installing the latest version breaks existing programs that work perfectly well with older versions. That’s life.

Thanks for the clarification @damonlynch.
I’m sorry if you had the perception that I was disappointed at RapidPhotoDownloader. All the opposite, I love it! And I believe it’s a great job.
My disappointment is towards PyQt (not the first time it has issues like this…). I do appreciate that you actually figured a way to overcome this.
As for pip and it being ‘broken’… I meant that the software management is ‘broken’, not the software manager. However, I may have made an unhappy word choice. Pip works perfectly (actually I develop in Python, I know it quite well), as you said. It’s just a pity whenever one has to ‘manually’ track the versions installed of any lib.
Please, consider my suggestion just as it is: a suggestion for improvement. I do believe that a stand-alone self-contained package would be amazing (e.g. AppImage, flatpak, snap, …).
Thank you in turn for your clarification.
Regarding a snap, appimage or flatpak, yes they have their benefits. When I tried to make a snap, a bug in the snapcraft tool meant I could not proceed further. The snapcraft developers encouraged me to fix the bug but I don’t have time for that, so that’s not gone anywhere. An appimage is nice from some perspectives, but it’s a lot of work to prepare it. Work on that was started but it took too much time and it’s been dormant for many months. As for flatpak, I haven’t looked at it, and have no plans to because again I have no time to do it. Plus I’m cautious because Rapid Photo Downloader needs to read and write plenty of places, like the shared thumbnails directory, etc. Is that even possible from a flatpak app?
Later this year I hope to be able to reactivate the PPA, building on the work others already did with creating the Debian package for Rapid Photo Downloader, and its many dependencies, several of which had never been packaged.
Is the snap yaml file somewhere where I can see it?
It’s a year old, so I guess things could have changed since then with respect to the spec, but in any case here it is:

Failed to install application: exiting...
… an error 2.
It seems I’m leveling up.
What should I try next?
It’s difficult to say without knowing what else is going on in your system. What I do know is that I’ve confirmed it works for me on Mint 18.3.
Since you are comfortable installing different versions of pip, I suggest doing some analysis of the problem. Upgrade pip to the latest version. Use pip3 to install the tarball itself, using the --verbose and --no-deps command line options. The verbose output should indicate the nature of the error on your system.
