As turned out, the reason was in the "Colors" option in Bitmap Designer, which I use to modify my installer style. This option makes some additional styling for controls:

You cannot change the color of these in Inno Setup itself, except by a custom build of Inno Setup or some addon DLL (see below).

All you can do is to re-implement these dialogs from the scratch:

• For the "browse" dialog: Handle the WizardForm.DirBrowseButton.OnClick and use CreateCustomForm and TFolderTreeView to implement the browse dialog. Download Inno Setup code and copy the existing implementation from SelFolderForm.pas.

  For an example of handling WizardForm.DirBrowseButton.OnClick, see
  How to display localized Program Files name (display name) during installation?

• For the "cancel" dialog: Implement the CancelButtonClick event function. Make sure you set Confirm to False to get rid of the default prompt. And implement your own. Again, use the CreateCustomForm.

It's a lot of work for a small gain. I'd not do it.

Instead, you can use VCL Styles for Inno Setup (DLL) to style Inno Setup windows (including all modal dialogs).
