If you click to view the log file and search for “Error,” you see log lines that resemble the following:

Note Some of the information in your log files will differ from this particular example.


This problem occurs because some components in Visual Studio 2012 are signed by a Certificate Authority that is not installed on Windows 7 or Windows Server 2008 R2. Computers that are not connected to the Internet cannot automatically download these certificates.


To resolve this problem, please download the root certificate updates that are described in the following Knowledge Base article:
  • 931125 Windows root certificate program members
Note The update applies to Windows XP, Windows Server 2003 and later versions. It will install on Windows 7 and Windows Server 2008 R2, which are the minimum supported Windows versions for Visual Studio 2012.

After you have installed the root certificate update, repair Visual Studio 2012 to install those packages affected by the problem that is described in this Knowledge Base article. To do this, follow these steps:

  1. Click Start, type Programs and Features, and then click Programs and Features in the search results.
  2. Find and select a product that is listed in the "Applies to" section.
  3. On the toolbar, click Change.
  4. Click Repair.
  5. Click Continue or Yes to elevate and continue with the installation, if you are prompted to do so.

More information

New root certificate authorities, which were created after Windows 7 and Windows Server 2008 R2 were released, enable strong signatures using a SHA256 hash. Computers that are connected to the Internet automatically download these certificates. However, computers that are not connected to the Internet or that have not already installed the root certificate update do not have the required certificate authority installed.

After the updated certificate authorities are installed, repairing Visual Studio 2012 will install any missing components. Therefore, Web Deploy 3.0 or any other affected components will be installed.
