When you try to install an update based on the IExpress installer in noninteractive mode by using a deployment tool such as SMS, Tivoli, or Altiris, you may receive an error message that resembles the following:
An unsigned or incorrectly signed file "c:\docume~1\admini~1.rma\locals~1\temp\ixp002.tmp\vb6ole~1.inf" blocked (server install).
This problem occurs because of an error in the .inf file that is contained in the IExpress package. Because of this error, the update installation is identified incorrectly as a driver installation. Driver installations that are applied in noninteractive mode must be digitally signed by the Windows Hardware Quality Lab (WHQL). When the update is not a legitimate driver update, the update package cannot be digitally signed by WHQL. In this scenario, updates that are based on an IExpress installer cannot be installed in noninteractive mode.
To work around this problem, install updates that are based on an IExpress installer in interactive mode.
