Preparing Microsoft Windows for TDV Installation
If you are installing TDV on Windows Server 2012 R2, you must disable User Account Control before installing TDV Server. Optionally, if you run into permission issues when running the installer, you can use this procedure to attempt to solve the issue.
To disable the User Account Control
1. From the Windows Start menu, select Control Panel > User Accounts > Change User Account Control Settings.
Change the setting to Never notify.
