Once you’ve received your CAC reader, the next step is to plug it in and verify your PC recognizes it. If you have selected any of the above readers, you should be good to go. Your computer may actually begin to install the appropriate drivers needed automatically. However if that doesn’t happen, follow these steps to get started:

For Windows 10 Users:

  • Right Click the Windows Logo found in the lower left-hand corner of your screen.
  • Click System, then Device Manager
  • Scroll down to where it says Smart Card Readers and click on the little triangle next to it to get started.

For Windows 7/8 Users:

  • Right Click My Computer and select Properties
  • Next select Device Manager and scroll down to Smart Card Readers
  • Select the little triangle next to it in order to get started.

After your drivers have been installed, it’s time to move on to the next step.


To access DOD websites from home, you first need to have DOD permissions certificates on your home computer. These are simple enough to acquire though.

Using InstallRoot will make this issue monumentally easy through their simple to follow wizard. You can download InstallRoot for Windows from the following links:


Once you have downloaded the program, simply run it. It will take you step-by-step on how to update your DOD certificates. After the installation, you can also verify that your DOD certs have been uploaded successfully.

This can be done by heading to your certificate management settings on your default Internet browser and checking to see if the certificates are listed.

After you’ve verified your DOD certificates, you next need to update your ActivClient–more specifically for your appropriate Branch of Service (if applicable).

ActivClient is a program that allows your computer to communicate with the chip on your CAC and relay that information between government websites. Making sure you have this installed is very important.

SO, you need to make sure that your ActivClient is up-to-date. Find your specific branch’s through the links below.

  • Army- In order for these links to work, you’ll need to copy and paste the entire link. Clicking directly on these will transport you to the homepage of AKO instead of to the download link. For Windows 32-Bit, use this link (32-Bit AKO LINK). For Windows 64-Bit, use this link (64-Bit AKO LINK).
  • Navy- Unfortunately, you need to get the client through your command’s IT personnel.
  • Air Force- The Air Force has not made it easy to acquire this software. However it is available for purchase at an ActivClient vendor such as here.
  • Marines- You’ll need to purchase ActivClient from an outside vendor. Check out this one!
  • Coast Guard- Purchase ActivClient from third-party vendor.
  • DOD Civilians- Acquire through vendor.

You Should Now Have CAC Access at Home!

But if not… There’s usually one particular reason. Your CAC card itself needs updating. Older versions of the card, do not meet the minimum requirements to access. To fix this, just head into your local PSD, and request a new CAC that does have access.

Problem 1: Receiving 'Your CA was not recognized. You should contact your CSA/LAN support team for assistance with DoD certs on this computer. You can install the latest DoD certs from...' error message when attempting to access the AF Portal

Information:The Cross Cert remover tool removes certificates which cause the cross-certificate chaining issue from Microsoft Local Computer and User Certificate stores. This will prevent your certificate from appearing to be issued by roots other than DoD Root CA 2 and being denied access to DoD websites. Some computers may have the Federal Bridge Certificate Authority's DoD Root CA 2 certificate installed. This conflicts with the DoD's DoD Root CA 2. You must remove the DoD Root CA 2 signed by the DoD Intermediate Root CA 1 in order to use the AF Portal with your CAC.


Cure 1-1: Follow the guidance in this PDF, slide 15 has download links for the Cross Cert remover tool.


Cure 1-2: If [after following guidance above] you're still having problems, go from this direct link:




Problem 2: Air Force users receiving 'There was a problem with this browser accessing your CAC for authentication. You may have pressed 'cancel' button in your browser's certificate selection prompt.

If this does not work or you are unable to complete this close all open browser windows and try again.

Information for Air Force personnel using Apple Computers: AROWS will not continue to the login page if it identifies your browser as non-compatible. This is easily fixed by having Safari report it 'is' IE. Go to Safari->Preferences ->Advanced and ensure the 'Show develop menu' check box is ticked. Now when you open NROWS and it gives the browser error, go to the Develop menu in the menu bar and select User Agent->Internet Explorer (any version 6.0 or greater) The 'Unsupported' page will refresh, Now paste the URL below back into the web browser again, you should be back at the login screen. This should work from the air Force Portal, or directly at the URL:

Try using User-Agent Switcher for Chrome

You can try this as well for AROWS, but, you'll need Google Chrome:

NROWS sets some narrow parameters when it comes to User Agent identification. Thursby software has figured this out. You'll need to build an AppleScript and use Google Chrome as your browser:
The first step is to build the AppleScript.

  1. Open Utilities > AppleScript Editor.
  2. Paste the code from below.
  3. Choose File > Save As…
  4. Select File Format: Application.
  5. Give the item a name and save.
  6. Then run the app.

Safari keeps crashing

Cac Card Reader For Mac Software Download Windows 7

An Air Force person emailed this fix to me: He would load his OWA, and the window would only stay open for about 10-20 seconds before OWA tried to open a calendar popup reminder. This popup would crash his Safari window, leading him to a frustrating 'Safari quite unexpectedly' error message. He could access other CAC websites like Air Force Portal, DTS, Leaveweb, and ADLS. He found a workaround while searching through Thursby forum that had the idea of going to Options, Accessibility, selecting Use the blind and low vision experience. This disabled the annoying calendar popup, now his OWA window no longer crashes Safari. He mentioned the visual experience is more basic now, but at least he can access his email.
