A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider.

Got this error while installing Visual Studio 2012 Ultimate on Win7.  The message and the log indicate the problem occurred installing WebDeploy 3.0.

  A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider.

Any suggestions?

I got the same error.

All I did was go to the setup media, packages folder, WebDeploy folder, and installed the x64 version by hand.

Works fine.

I'm in the process of getting a KB article up about this. The resolution is to install the root certificate update from http://support.microsoft.com/kb/931125 and repair the installation.

I had to use "Modify" not "Repair" because the failed web development feature and many others (originally queued for install after it) were not installed in the first place.

Here is a direct download link to the root update tool from MS:

http://download.microsoft.com/download/3/A/4/3A423151-FEAB-43FB-902D-679023BF159F/rootsupd.exe

It doesn't show any dialogs or success message. Just run it then wait 30 seconds.

My fix was to download the complete ISO installation rather than the web installer (web installer gave me errors).  Once I did that, I unzipped the ISO to a folder (rather than running the setup from the zip directly - which will still get this error) and then I was able to install with no errors.  Hope this helps someone out there!  Download, unzip, install.
