Suppress Prompts About Unsigned Drivers on Windows Operating Systems
Before Vista
If you are installing a beta or RC version of VMware Tools in a Windows Server 2003 or earlier guest
operating system, you can use a computer properties setting to suppress prompts that interfere with
automatic installation of VMware Tools.
The version of VMware Tools included in a beta or release candidate version of a VMware product usually
has some drivers that are signed only by VMware. If you are installing one of these versions in many virtual
machines that run Windows Server 2003 or earlier guest operating systems, or if you plan to install VMware
Tools from the command line, you can suppress prompts about unsigned drivers. If you do not suppress the
prompts, during a VMware Tools installation, a message box appears several times and requires you to click
Continue Anyway to complete the installation.
