Although you can select a certificate to sign an application in the PocketBuilder Project painter, when you deploy the application from a Windows Vista machine, an error message displays in the Output window indicating that the application signing has failed. The Windows API does not return a reason for the signing failure. However, you can sign applications in this way from PocketBuilder projects that you deploy from Windows XP, Windows 2000, or Windows 2003 platforms. [CR 477282]
