The exit code 2001, means "The installation failed the authorization check, may indicate an expired version". To know more about the exit codes goto InstallAnywhere help and look in to Installer Exit Codes page.
I believe that the eval-mode-built installers stop working after 3 days. From the Important Information section of the release notes:
Evaluating InstallAnywhere Note that if you have not purchased a license for InstallAnywhere, you can install it and use it for a limited number of days without setting up the licensing. When you are using InstallAnywhere in this scenario, it operates in evaluation mode. The licensing wizard that InstallAnywhere displays whenever you launch InstallAnywhere in evaluation mode shows you how many days are left in the evaluation period. If you do not set up the licensing within the evaluation period, InstallAnywhere stops working when the evaluation period ends. You can set up licensing at any time before or after the evaluation period ends.
When you use InstallAnywhere in evaluation mode, there is a time limit for running installers that it creates. If you build an installer in the evaluation version of InstallAnywhere, your installer will stop working after 3 days.
