Qt Creator Install problem on Windows

Hi all, I'll try to keep this brief.

I was running Qt Creator 5.15.2. I kept getting prompted to update to Qt6, I've ignored this many times and eventually I set about updating to Qt6.

Long story short, got Qt6 installed but it will not start. So i removed the whole install and started again. Once I got Qt6 installed I found the same problem as before, it will not start. Looking in the Star Menu, I find an entry for Qt6, click the icon and boom, error!, again.......I do not know what I am doing wrong.

The icon in the Start Menu is a command line icon, which of course, starts a cmd window.........ermmm?, what?, where is the exe shortcut?

I am using Windows 7 (still) and assume that because I had Qt Creator working nicely just a day or so ago, that my outdated OS may not be the problem.

Can someone point me in the right direction with regard to the installed for Qt please?, I was using MinGW 32 bit with my last working install. I have tried many many times now by choosing MinGW 32 (don't recall version numbers) but still end up with a command line entry for Qt in Start Menu.......I'm so lost, any ideas appreciated!

I chose the "qt-unified-windows-x86-4.2.0-online.exe" for community/open source, so I'm sure I have the right installer...?

Regards,

Qt6 doesn't support Windows 7. The best thing you can do is revert to Qt 5.15.2 and an older Qt Creator version.

@Crisian-Adam-0 - Thanks, I was not aware the Qt6 doesn't support Windows 7. I should research better!.

As you point out, I already tried going back to 5.15.2 but I do not get a shortcut installed for the exe. Instead I get a command line icon, where is the exe?, seems I have unwittingly installed the wrong type of Creator. Never had this before now.

Also Qt6 doesn't come with a 32 bit MinGW build. It's 64 bit only.

qt-unified-windows-x86-4.2.0-online.exe is the Qt Online Installer, which usually installs the latest Qt Creator version, you can only select Qt versions but not a Qt Creator version.

For Qt Creator go to https://download.qt.io/official_releases/qtcreator/ in order to get older versions. At https://download.qt.io/archive/qtcreator/ you can get the rest of the versions (<4.15)

Okay so ignoring Qt6 completely, but what I do not understand is why the installer offers "Custom" from which I selected 5.15.2 but leaves me with a garbage installation and a Qt6 command line icon when I did not choose Qt6....sorry I'm lost.

Trying to go back to 5.15.2 still leaves me with a command line icon to start Qt.......again, why?, where is the exe........pretty certain I never had this complication when installing Qt Creator before....oh and when clicked, I get en error regarding QT6...?, weird. I need to clean up and start again sigh.

Anyway, I found an offline installer from Qt; "qt-opensource-windows-x86-5.12.12.exe" and will try that. If that doesn't help, I will have a try with the links that you provided, thank you.

Whew!, finally!, a working install of Qt Creator 5.02 based on 5.15.2. using qt-opensource-windows-x86-5.12.12.exe

Just compiled one of my apps and all is working well.

Thanks for your help and information @Crisian-Adam-0 :)

You can also get Qt Creator 6 builds with Qt5 at https://download.qt.io/snapshots/qtcreator_qt5/6.0/
You don't have to get stuck with Qt Creator 5 :)
