AdminStudio Activation Error: The quantity specified exceeds maximum quantity allowed (0).

[#1]

This article provides information regarding how to resolve the activation error: "The quantity specified exceeds maximum quantity allowed (0)".

Symptoms

Your attempt to activate your license is denied, and the following message is displayed:

The quantity specified exceeds maximum quantity allowed (0).

Cause

This activation error indicates that the license you are attempting to activate has already been activated on another machine.

Resolution

To resolve this error, it will be necessary to return the license to the account on the activation server. This process is sometimes referred to as a deactivation.

You can return the license by uninstalling the application or by clicking the Return License button (available in AdminStudio 11.x and up). The Return License button is located in the About dialog box (which is displayed when you click About AdminStudio on the Help menu).

Starting with AdminStudio 8.5, you can also return the license from the command line, by executing the return command as follows.

1. From the command-line change directories to the appropriate default path:

AdminStudio	Default Path
AdminStudio versions 8.5 and 8.6	C:\Program Files\Macrovision\AdminStudio\Common
AdminStudio versions 9.x and up	C:\Program Files\AdminStudio\<VERSION NUMBER>\Common

Note: For 64 bit machines, the default location will be located in the Program Files (x86) Directory.

2. Execute the following command:

• AdminStudio: TPSconfig /return

I am facing this issue. Though the VM where AS was installed has been rebuilt in the meantime and no AS installed on it now. Is there any other way around?
