    NOTE: Symantec Technical Support, with the assistance of its customers, has compiled information concerning Microsoft Windows Installer error messages. This article is provided for reference. Although specific solutions are outlined, there may be multiple causes for some of the Windows Installer errors, and the solutions discussed may not resolve the error in all circumstances.

    The assembly specified in the error must be strongly named. A strong name is made up of the full class name including the namespace, the version number, culture information (which can be null if culture neutral), plus a public key and a digital signature.

    Please view Microsoft's MSDN article, "Creating and Using Strong-Named Assemblies", regarding how to create a strongly named assembly. A link to this article has been provided.

    The full error messages for 4-digit Windows Installer error codes can be found in the Windows Installer SDK. More information may also be available at Microsoft's web site .
