QtCreator: No valid kits found

Question

Installed just the IDE on Windows 7. I want to create a Plain C++ Project (Non-QT Project); however I get an error: No valid kits found. When I click on O

Answer 1

I had a similar problems after installing Qt in Windows.

This could be because only the Qt creator was installed and not any of the Qt libraries during initial installation. When installing from scratch use the online installer and select the following to install:

1. For starting, select at least one version of Qt libs (ex Qt 5.15.1) and the c++ compiler of choice (ex MinGW 8.1.0 64-bit).

2. Select Developer and Designer Tools. I kept the selected defaults.

Note: The choice of the Qt libs and Tools can also be changed post initial installation using MaintenanceTool.exe under Qt installation dir C:\Qt. See here.
