Necessity of a 64bit Windows version?

[jsbackus]

I wasn't part of the original conversation, so please forgive my ignorance, but are there any situations where a 64bit Windows version is required? I understand the need on Linux, since multilib isn't free. But, to my knowledge, there isn't a big difference between 32bit applications and 64bit applications, as long as you don't need the extra resources. I'm willing to support a 64bit version if there is a legitimate requirement for it. If not, then I'd like to reduce the number of build permutations.... Thoughts?

Looks like the qtx64 project at SourceForge has been abandoned and files removed. There is a qt64-NG project that has been abandoned, but at least there is still an installer for Qt 5.5.0.

There is a wiki page on the official Qt wiki for building with MinGW-64. It seems to contain a mix of outdated and updated information, but at least is a good starting point for anyone wanting to build Qt for Win64.

You can download Qt from official site https://www.qt.io/download-open-source but x64 build are available only for Visual Studio compilers.

@Nucleoprotein Thanks! That is what I was afraid of. For the time being, I'd like to stick with the MinGW build. If there is a compelling reason to build a 64bit version for Windows, we may revisit this.

AntiMicro is no longer maintained. There were no bigger fixes since 2017.
There is a new recommended version of this app called AntiMicroX.

As a part of cleanup, this issue will be closed and repository will be archived.
If you find this issue relevant also for that new version of application you can create a new issue (or discussion) there (but firstly check it, because many issues of the old app are fixed and there are some new functionalities implemented)
If you will decide to create a new issue for AntiMicroX remember to mention this issue for reference.
