    I've been doing Qt/C++ on Windows for about ten years, mostly desktop apps that get deployed to machines I can't touch. The recurring pain is never in the code — it's in the last mile. Things that have bitten me, roughly ordered by how much time they cost: "no Qt platform plugin could be initialized" — the classic. Usually platforms/qwindows.dll missing, or present but in the wrong place, or built with a different kit than the exe. QML app ships, launches, shows a blank window, logs nothing. Missing QML modules that windeployqt didn't collect because --qmldir wasn't right. Every HTTPS request fails silently. Took me a while to find: Qt 6 needs the TLS backend plugin (qopensslbackend.dll / qschannelbackend.dll), and without it QNetworkAccessManager just returns generic errors with no clue why. 0xc000007b on the customer machine. 32/64-bit mismatch, or a wrong-arch vcruntime140.dll already sitting somewhere in PATH. Runs fine on my box, missing MSVC redistributable on theirs. Antivirus flags the exe. Unsigned binary. Fonts and widget styles look completely different on another machine — missing styles/ plugin. My current process is: build, run windeployqt, then manually walk the deploy folder against a checklist I've accumulated over years, then test on a clean VM. It works, but it lives entirely in my head and it's easy to skip a step when I'm in a hurry. So, for those of you shipping Qt on Windows: Which of these have bitten you, and which one costs you the most time? What's the failure mode that is NOT on my list? I'm fairly sure I've just been lucky with a few. Not selling anything here — I'm trying to figure out whether the checklist in my head is a shared problem or just my own paranoia.

    Thanks a lot for all this information. It has helped me get clarity on the questions that have been bugging me for weeks. I can now decide better what I want to do, and why. I will definitely share these with them ideas about unifying the UI for mobile and desktop with Qt, as it seems like it doesn't necessarily warrant replacing starting their application from scratch, only their UI code will get replaced (and its bindings).

    This had been reported to Squish technical support team, and closed on behalf of the reporter. Unfortunately it was not possible to identify a clear cause so far.

    [image: 01776ece-1308-4e3c-98fd-2749b3a4e221.png] Challenges faced: So when it came to building the d-pad, I was absolutely lost and was trying to approach this problem by drawing and arc instead and so I was reading about PathArc, and so it was getting so complicated, then I did see how it was implemented in the solution. repo: https://github.com/Meehir5907/QML-for-Beginners-Challenges/tree/Intro-Qt-Quick-My-Sol/StartingProject

    Unless I misunderstand, this topic was written when this forum used Textile, which explains why some of the above have broken formatting. This question is therefore no longer relevant for this forum. That being said, to anwer this question should anyone else land on this topic from a search engine, this should (now?) be possible. 🅭🄍
