I registered Actipro license at the very beginning of my application as bellow.
My application works well in most test machine. But it fails in one of them since I ever install and uninstall Actipro component using evaluation option.
1. Install the ActiPro demo version using evaluation option.
2. Uninstall it
3. Install my application
4. Start up my appliction and display syntax editor, then a license dialog is shown.
In such a case "WinFormsControlsLicenseProvider.RegisterLicense" feature is broken. I think it is a bug.
