Why Block Craft 3D：Building Game won't install

Block Craft 3D：Building Game downloads from AppLoko but won't install? Below is what in this particular build (4.0.0, 112 MB) can block the install, and what to do about each case. Everything here comes from the installation file we serve, not from generic advice.

Which Android version is required?
The first thing to check is your Android version. This build needs Android 6.0 or newer: on 5.0 and older the system installer rejects the package and shows “App not installed” without explaining why. Your version is in Settings → About phone → Android version.
How much free storage is needed?
The second is free storage. The file itself is 112 MB, but installing needs roughly 280 MB: the installer keeps both the package and the code unpacked from it on disk at the same time, and frees the difference only afterwards. When storage runs short the installer shows the same “App not installed”.
Does this build fit my processor?
This build carries native code for 64-bit processors only (arm64-v8a), so it will not install on a 32-bit phone. You can read the architecture in an app such as CPU-Z under Instruction Sets, or with adb shell getprop ro.product.cpu.abi. If it says armeabi-v7a without arm64, you need a different build.
Why won't it install over the Google Play copy?
This build is signed with the AppLoko catalogue key rather than the developer's. That is why it cannot install over a copy that came from Google Play: Android compares signatures and refuses, which on screen is the same “App not installed”. Uninstall the existing copy first, then install this file.
Which permissions will the app ask for?
After installation Block Craft 3D：Building Game will ask for dangerous permissions: POST_NOTIFICATIONS, READ_EXTERNAL_STORAGE. They are requested on first launch, not during installation, so denying them does not break the install — but some features will not work without them.
It installed but does not work — why?
The build allows unencrypted HTTP traffic. That does not affect installation, but with a private DNS, a VPN or a blocker enabled some of the app's requests may not go through — which looks like “it installed but does not work”.
Has the file been scanned?
The file is checked: VirusTotal, 74 antivirus engines, no detections. Android's warning about installing from an unknown source is normal — it appears for any file that did not come from Google Play; to continue, allow installs for your browser or file manager in Settings → Apps → Special access.
What if none of this helped?
If none of the points fit, download the file again: an interrupted download produces the same error message. The checksum is printed on the version page, so you can verify the file before installing.
