Software update removal information
To remove this update, you must uninstall the Windows Media Format Runtime by using Add or Remove Programs.
During the license acquisition process, content services can detect whether their end users have updated their computers by checking for component versions. Using the Windows Media Rights Manager SDK on the licensing server, the content service can retrieve version information from the client and then determine how to continue. The license server can determine whether the client has the update by using one of the following methods:
- Determine the version of the user's operating system.
At first, the update to the Windows Media DRM system is available only to users of Microsoft Windows XP. Use client-side code to determine the version of the user's operating system.
Content services may choose to issue licenses to computers that the update is not yet available for. Or, content services should notify their users that licenses will not be available until the DRM run-time component for their operating system becomes available.
- Determine the version of the Windows Media Format run-time components on the client.
Determine the version of the Windows Media Format run-time component that the user's player is based on. Use the WMRMChallenge.ClientVersion property to retrieve this value. An updated client has version 10.00.00.3802. To install the updated run-time components, redirect the user to the URL that is mentioned in the "More Information" section.
- Determine the security version of the DRM component for individualization.
Determine the security version of the DRM component. The version number indicates whether the client must individualize its player. Although the Windows Media Rights Manager SDK provides several ways to determine the security version, we recommend that you use the WMRMLicGen.GetClientVersion method because the resulting value is digitally signed. This digitally signed value cannot be tampered with. The value for the pvarVersion parameter of this method indicates the security version a.b in the format:
An updated client has a security version of 2.5 or a later version. If you see a value that is less than or equal to 516, you know that the client requires individualization. You can redirect users to the following Microsoft Web site to initiate individualization:
a*256 + b (For example, a security version of 2.4 returns a value of 516.)
Before the licensing servers can determine the versions of client components, you must update the configuration information on the licensing servers. To do this, visit the following Microsoft Web site and then click Download the latest License Server information
You must perform this update on each computer that is running Windows Media License Service.
