Open-Source Version Installation Problems

Question

I am trying to install the open-sourced version of Qt using the web installer. It downloads everything and installs up to about 50% and then the errors start popping up. I get the following errors:

Error during installation process (qt.qt5.51Z5.win64_rnsvcZ0‘l5_64):

I have tried cancelling the install and then reinstalling it, I have tried redownloading the exe, but nothing seems to help.

Answer 1

These errors are annoying. The installer is trying to run the sdktool to set up Qt build kits (compiler details/etc) in QtCreator, which it just installed, but can't, and the message never tells you why exactly.

In the past for me this has turned out to be a permissions problem -- the user sdktool is running as (from the Qt installer) doesn't have permissions to modify stuff in QtCreator installation folder. (Which I thought was strange since I always run everything as admin anyway.) So my solution has been to ensure the QtCreator install folder has write permissions for all Users on my system. Actually I just modify permissions on the whole Tools folder Qt installs. This works (for me) even while the installer is running, after the first error prompt I can go in an change permissions and tell it to try again.

Another option is to ignore those errors and set up the compiler kits manually in QtCreator, but that's a hassle and it certainly helps get started when all that is set up for you already.

Another option would be copy those failed sdktool commands and run them manually after the installation. I've done this a few times "in a pinch" but again it's a bit of a hassle.

Thank you for your help. I will try your suggestions. I marked this as answered. – Faery

This helped me too while installing and it gave an error like Cannot download archive cdn.qt.io/qtsdkrepository/windows_x86/desktop/tools_maintenance/…: The system cannot find the path specified. – Presser

It would be nice also to provide the modifying permission command that you've used. – Oh

@Oh I use the Windows GUI to set permissions. A "screeencast" with how to set permissions in Windows I thought was out of scope here since there are a myriad of guides to follow online if one needs it. As mentioned I give all Users on the computer write permission to the Qt install Tools folder and subfolders. Others may want/need more granular permissions. – Venosity

@MaximPaperno in my case (ubuntu 18.04), it seems the online installer forces me to install Qt Creator 7 which uses qt 6 (i.e. qt 6 is not compatible with 18.04 LTS). – Oh

Answer 2

Just in case someone else is having similar issues in Mac OS X with latest Qt6 and Qt Creator 4.14. The sdktool path in the command is wrong. Manually create a symbol link in the Qt\ Creator.app/Contents/Resources/libexec/ (sdktool is in the parent folder of this), it should be working fine.

from this bug report: bugreports.qt.io/browse/QTBUG-89966 I was able to run the suggested commands which mirror this answer to fix the issue: cd "$HOME/Qt/Qt Creator.app/Contents/Resources/libexec/" ln -s ../sdktool – Bierman

Answer 3

I had a similar issue. But my issues was due to having an old version of Qt Creator that had no libexec folder under $HOME/Qt/Qt Creator.app/Contents/Resources/. So I suggest updating Qt creator if you run into this.
