The binary 'C:/Program Files (x86)/QT Designer/bin\assistant.exe' does not exist

[H. Martins]

Hi.

I am using QT Design ver 5.11.1

Clicking Help->GT Designer help i get the following message

"The binary 'C:/Program Files (x86)/QT Designer/bin\assistant.exe' does not exist"

Well, the bin folder does not exist inside
C:/Program Files (x86)/QT Designer
and the required .exe is located in
C:/Program Files (x86)/QT Designer

What can I do? Should I create a bin folder and move assistant.exe to this new bin folder?

Thanks
H. Martins

Hi and welcome to devnet,

How did you install Qt ?
This path is rather unusual

[H. Martins]

Well, I installed double clicking "Qt Designer Setup.exe" ... the usual way.

I uninstalled it and re-installed again and it keeps saying the same.

Are there any 'funny' files it stored somewhere that I could delete manually before re-install?

After uninstall the folder "C:/Program Files (x86)/QT Designer" disappeared so it looks like there was nothing left to contaminate th re-install.

I even looked to the OS 'set' and there is nothing there concerning Qt, before or after re-installation.

I am using Windows 10 Pro/64 22H2

Thanks
H. Martins

@H-Martins

Check your PATH variable. Is there something Qt-related?
If your Qt path is set to something like C:/Program Files (x86)/QT Designer, it is probably looking for a [...] / bin/assistant.exe in there.

Usually the assistant.exe is located in <QT_DIR> / <YOUR_KIT> / bin / assistant.exe

Edit:
The mix of forward and backward slashes in the path shown in the error message looks weird. Like it was concatenated from two different vars or sub-paths.

@H-Martins Where did you get that installer from ?

From as far as I remember, there never was a standalone installer for Designer only.

[H. Martins]

There is nothing concerning QT in the path.

I created
"C:\Program Files (x86)\Qt Designer\bin"
and moved assistant.exe to bin

Now it says

I am using QT Designer with Pyton and PyCharm.

Like @SGaist asked before, how and where have you installed Qt?
(the whole framework, not the "Development tools" like Qt Designer)

It's not the "usual way". Usually you would use the Qt Maintenance Tool / Online Installer to download and manage your Qt installations OR you build Qt from source.

It feels that your installation is messed up somehow or there are components missing.

Edit:

Are you talking about this Qt Designer Setup.exe by any chance?
This is not official Qt. "Somebody" built a standalone QtDesigner installer.

Maybe you should have mentioned earlier :)
