Known issues and workarounds

WarningWarning
The HCK for Windows 8.1 Preview cannot be used to certify machines running Windows 8.1 RTM.

  • We recommended that you remove any previous version of the HCK before installing the RTM version. Installing over a previous installation of the kit isn't supported and can result in errors.

  • HCK Controller installation may fail if the system contains SQL components from a previous installation. We recommend installing the HCK Controller on a clean install of Windows Server 2008 R2 x64 with service pack (SP1) or Windows Server 2012.

  • Installation logs are written to the %TEMP% folder. This folder is normally deleted for Remote Desktop sessions. We recommend installing the HCK Controller and HCK Studio at the console rather than through Remote Desktop. Or, you can use Temporary Folders policy settings to prevent the install logs from being deleted.

  • On x86 and x64 clients, UEFI Secure Boot must be disabled before installing the HCK Client software. This is necessary to allow HCK Client installer to enable TESTSIGNING mode. UEFI Secure Boot should only be enabled while running Secure Boot tests.

  • We recommend that you install the kit with a wired network connection. An unreliable Wi-Fi connection can result in improper content installation and missing tests.

  • HCK Controller, Studio, and Manager aren't supported in Virtual PC or any third-party hypervisor environment. We also do not support hyper-v unless noted in the test documentation.

  • In some cases the UI will not refresh when setting a machine to “Ready” in HCK Studio. We recommend restarting HCK Studio if a machine has been initializing for a long period of time.

  • If there is a network connection issue between a controller and its clients while sending data the client will stop responding and the running task cannot be cancelled in the HCK Studio UI. We recommend cancelling the task in the HCK Manager.

  • When you create a device certification project, select a device before you select a computer from the Systems view. The first time that a job is run on a project, a pre-requirement job is run on the client called "Windows Logo Kit – Prepare client for submission". The UI doesn't reflect the status of this job, which can take 5–10 minutes to run. You can track progress by using the HCK Manager app in the Job Monitor.

  • Signtool can't be used to sign an .hckx file. The HCK Studio UI or Object Model is the only way to sign an .hckx file. The Studio UI is able to query the personal certificate store for code-signing certificates, or it can use a non-password–protected certificate file. To sign an .hckx file using a certificate contained in a password-protected file, the Object Model must be used. It's easily automated by using PowerShell.

  • Webcam Min Resolution for integrated cameras - The following test has been updated to reflect the relaxation of the requirement for minimum resolution for USB rear cameras. USB camera requirement has been updated to allow a minimum resolution of 1080p @ 30 Fps for rear cameras.
