Until yesterday when I downloaded the 4.1 update, I didn't have the Flash build target in the the Build dialog. With the 4.1 update, I now have it. However, the build buttons are grayed out, and there is a label and a button with the following text: BuildSettings.NoSecretPlatform and BuildSettings.NoSecretPlatformButton. I supposed those should be something along: contact sales. Best, Alain-Daniel
I just purchased a Flash License and am using Unity 4.1 and get the same message with greyed out export options. Will file a report with sales as well.
