Password string is empty
You checked the Tarma package Password attribute, but did not specify a password. As a result, the installation package cannot be encrypted.
Background information
The Password attribute specifies that the installation package will be protected by a password-based encryption. This requires a non-empty password.
Solution
Enter a password after the Password checkbox, or click Generate... to let InstallMate generate one for you. Alternatively, if you don't want to protect your installation package, clear the Password checkbox.
