InstallRoot automates the install of the DoD certificates onto your Windows computer

To access DoD websites from your computer, you need these certificates on your computer.  You may need to reinstall the certificates if the CAC enabled web site won't load, the website you are visiting is prompting you with the message there is a problem with the website's Security Certificate / site is not trusted, you have received a new CAC, or your DoD website worked up until recently and doesn't now.

 Apple computer users follow these instructions

Windows RT users follow these instructions

Chromebook users follow these instructions

InstallRoot is created by DISA for Windows computers, if you have any problems with this file, please contact them. 

NOTE: If you do not want to install the InstallRoot program, you can install the certificates manually by, following these instructions.

Windows users, Download InstallRoot 5.2 from:

MilitaryCAC (.msi version) (26.4 MB),

MilitaryCAC (.zip version) (25.4 MB), or

DISA (.msi version) (26.4 MB)

(It is the same file [except for .zip version] from 3 different web locations, in the event one of the links don't work)

If you have Firefox installed, you may see 2 or 3 tabs

NOTE: I have one report that a person had to select Restart as Administrator.  This was the first and only person in the several years this program has been in existence that I have heard this.

InstallRoot not updating was fixed in InstallRoot 5.2

Select Yes, (this screen may show 2 - 3 times) as it is installing the DoD Root CA 2, 3, 4, & 5 certificates

.

Select OK (your number of Adds will vary)

.

How to verify you have the certificates installed

Open Internet Explorer, Select Tools (Gear), Internet Options

Select Content (tab), Certificates (button)

Intermediate Certification Authorities (tab) scroll down the Issued To (column) to the letters DOD to verify you have:

DOD EMAIL CA-33 through DOD EMAIL CA-34

 DOD EMAIL CA-39 through DOD EMAIL CA-44

 DOD EMAIL CA-49 through DOD EMAIL CA-52

 DOD ID CA-33 through DOD ID CA-34

DOD ID CA-39 through DOD ID CA-44

DOD ID CA-49 through DOD ID CA-52

DOD ID SW CA-35 through DOD ID SW CA-38

DOD ID SW CA-45 through DOD ID SW CA-48

and

DOD SW CA-53 through DOD SW CA-58

also verify the Root certificates installed (as sometimes the Antivirus program doesn't allow these to be installed)

Open the Trusted Root Certification Authorities (tab) verify you have:

DoD Root CA 2 through DoD Root CA 5

If you see "There is a problem with this website's security certificate" after installing the DoD InstallRoot file or the Red Certificate error below, follow this guide

PROCEED TO STEP 4 - INSTALL ACTIVCLIENT

The Cross Cert Remover tool is "supposed" to be an automated way of removing some certificates that cause access problems.  From what I've experienced, you still need to follow my guide [slides 16&17] and manually remove certificates the Cross Cert Removal Tool fails to remove.  Feel free to use if you want to waste your time.

You can install both the InstallRoot and the Cross Cert Removal tool in one single file which was created by NETCOM (Army Network Enterprise Technology COMmand)

This file is created for Home Users ONLY, you can download it from:

Information:

A certificate is a digital document providing the identity of a Web site or individuals.  DoD Web sites use a certificate to identify themselves to their users and to enable secure connections.  If you are receiving a warning that a site is untrusted / insecure, you will need to install the "DoD Certificates."  In order to access sites enabled with a DoD PKI certificate without being prompted to accept the DoD Certificate chain at each log on [like Firefox and Safari do], people using Internet Explorer and Chrome should install the DoD certificates.  These are separate from the personal certificates that are on your CAC, but they are related.

Root Certificates

How can you (or your web server) trust the identity of someone over the network?  An infrastructure of trusted third parties has been put in place to distribute trust between end-users.  This infrastructure verifies that we are who we say we are.  If we trust the DoD PKI infrastructure, then the infrastructure can vouch for us to trust others that have certificates issued from the DoD PKI.

The DoD PKI Infrastructure is comprised of two Root Certification Authorities and a number of Intermediate Authorities.  If all of the DoD root certificates are not installed on your computer, various applications will not be able to trust all DoD PKI certificates.
