Solved Problems with Adding Qt Library Packages via Maintenance Tool: ReferenceError
First of all, I am completely new to using Qt Creator so I do not have that much experience with it. I had downloaded version x86 4.0.1 on my Windows 10 computer very recently, but I discovered a problem with Qt Creator in that when I was trying to run a project it was saying that Kits were missing, and in trying to solve the problem with Kits I found out that the Qt version was being displayed as "None" according to the IDE. So, after reading some posts it seems that I was missing a Qt Library so I ran the Maintenance Tool in the Qt directory, successfully logged into my account, and selected version 5.9.3 to install (I had tried installing version 6 and above but it came up with a reference exception, similar to the one that I will describe). I hit Update and then at the 40% mark it shows an error which is the following:
ReferenceError: registerQtCreaterDocumentation is not defined
I try again and I receive the same error at exactly the same percentage mark. In such a case I do not know what to do when I am hit with this error when attempting to download and install a Qt Library. After I click "Okay" on the Error dialogue box it then takes me to the "Finished" tab where I cannot do anything else except try again (which has failed for me) or to quit the installer. I would be much obliged for assistance in this matter.
Try uninstalling Qt completely. Then run Qt installer again, and in package selection pick any Qt version you need, for example a build for MinGW compiler. Should work.
Thank you very much for that suggestion. It looks like resolving the problem truly was as easy as uninstalling Qt completely and then reinstalling it again. During the installation process, I selected the default option instead of custom installation and everything went fine. Additionally, the problem with Kits was also resolved.
