Symptoms

Assume that you use Windows Internet Explorer to access an Internet Printing Protocol (IPP) server website on a Windows 7 or Windows Server 2008 R2-based computer. When you try to install a particular third-party color printer driver from the website, the installation fails. Additionally, you receive the following error message:

Printer Installation Failed
Not Empty

Cause

This issue occurs because both the .webpnp file and the driver package contain the same .icm file. Therefore, when Internet Explorer starts the Wpnpinst.exe process, the process detects the conflict and then reports an error.

Windows 7 and Windows Server 2008 R2 file information notes


Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.

  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    Version

    Product

    Milestone

    Service branch

    6.1.760
    0.16xxx

    Windows 7 and Windows Server 2008 R2

    RTM

    GDR

    6.1.760

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows 7 and for Windows Server 2008 R2" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are critical to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
