Windows Installation Prerequisites

• Make sure the version of Windows running on the target system is supported for data encryption. If you want to encrypt the boot drive, make sure the Windows version is supported for boot drive encryption as well. For details, see Supported Platforms.
• Make sure the default language for the Windows operating system is English. The HyTrust DataControl Policy Agent uses scripts that parse the output of Windows commands, and those scripts may give unexpected results if the command output is in a language other than English.
• Make sure that HyTrust KeyControl is installed and the cluster is configured properly as described in Basic KeyControl Configuration. The cluster must be healthy. You cannot register the Policy Agent with a degraded KeyControl cluster.
• Make sure the target system is partitioned correctly and you know which partition you want to encrypt. In addition, the partition must be assigned a drive letter or folder mount through the Windows Disk Manager. For details, see your Windows documentation.
• If you are using Windows 2008R2 or Windows 7 and you want to manage the Policy Agent through the HyTrust Policy Agent GUI, make sure that the Microsoft .NET framework version 4 or higher is installed on the target system. For details, see http://www.microsoft.com/en-us/download/details.aspx?id=17851.

• If you are using Windows 2012 R2 please ensure the following: 

  • The Microsoft .NET framework version 4.5 or higher must be installed on the target system. For details, see https://dotnet.microsoft.com/download/dotnet-framework/net452.

  • You must upgrade powershell by installing Win8.1AndW2K12R2-KB3134758-x64.msu. For details, see https://www.microsoft.com/en-us/download/details.aspx?id=50395.

• If you want to encrypt the boot drive, see the prerequisites in Windows Boot Drive Installation Prerequisites.
