Does anyone knows how to get the api documentation installed to qt.

But… how did you install creator?

If you build Qt Creator yourself: Did you do “make docs”?

I installed using ./Qt-installer.run. It should work since I have previous version installed and got no problem. But during the installation, I found an error and ignore that. I guess there is some missing component when I downloaded the installer. Weird stuff.

The “installer” is the SDK installer? If so, run the maintenance tool and install the doc packages.
