This happens when your application does not specify comtl32 v6 in the application manifest.

Typically that manifest setting would be arranged in your project settings. Look under Application. You should see that Manifest File is set to Auto Generate, and that the Enable Runtime Themes item is checked. That is the IDE project setting that gives you comctl32 v6.

There are other ways to specify comctl32 v6 in your manifest. You might be supplying a custom manifest, for instance. If that is the case then you'll need to dig into what is going wrong with your manifest.
