2. Update your graphics card driver

An outdated or incorrect display card driver could also be the culprit to your Armored Core VI: Fires of Rubicon not launching problem, so if Armored Core VI: Fires of Rubicon doesn’t launch when your computer meets or is above the required system specs, it’s likely that you have a corrupted or outdated graphics driver. So you should update your drivers to see if it helps.

To make sure that the driver update is done properly, you need to first uninstall the older driver. To do so:

1. On your keyboard, press the Windows key and the R key at the same time, then type devmgmt.msc and hit Enter.
   
2. Double-click to expand the Display adapters category, then right-click your display card and select Uninstall device.
   
3. Tick the box for Attempt to remove the driver for this device and click Uninstall.
4. Repeat the same to remove the driver for your other display card if you have one.
5. Then download and update your graphics card driver.

There are mainly 2 ways you can update your graphics driver: manually or automatically.

Option 1: Update your graphics driver manually

If you’re a tech-savvy gamer, you can spend some time updating your GPU driver manually.

To do so, first visit the website of your GPU manufacturer:

• NVIDIA
• AMD
• Intel

Then search for your GPU model. Note that you should only download the latest driver installer that’s compatible with your operating system. Once downloaded, open the installer and follow the on-screen instructions to update.

Option 2: Update your graphics driver automatically (Recommended)

If you don’t have the time, patience or skills to update the driver manually, you can do it automatically with Driver Easy. Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to be troubled by the wrong driver you would be downloading, and you don’t need to worry about making a mistake when installing. Driver Easy handles it all.

You can update your drivers automatically with either the 7 days free trial or the Pro version of Driver Easy. It takes just 2 clicks, and you get full support and a 30-day money-back guarantee with the Pro version:

1. Download and install Driver Easy.
2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
   
3. Click the Activate & Update button next to the flagged device to automatically download and install the correct version of this driver.
   
   Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (You’ll need the Pro version for this – when you select Update All, you’ll get a prompt to upgrade. If you’re not prepared to purchase the Pro version yet, Driver Easy provides a 7-day trial at no cost, granting access to all Pro features like fast downloads and easy installation. No charges will occur until after your 7-day trial period ends.)
   
4. Restart your computer for the change to take effect.

Try to launch Armored Core VI: Fires of Rubicon again to see if the latest correct graphics card driver helps. If this fix doesn’t work for you, try the next fix, below.

3. Check the Windows firewall settings

Certain firewall settings might interfere with the connection between your computer and Steam’s servers, thus the launching problem with some games in Steam. To see if this is your case, you can temporarily disable your firewall for testing purposes. To do so:

1. On your keyboard, press the Windows logo key and R at the same time. Then copy and paste control firewall.cpl and click OK.
   
2. From the left menu, select Turn Windows Defender Firewall on or off.
   
3. Select Turn off Windows Defender Firewall (not recommended) for Domain network, Private Network and Public network. Then click OK.
   
4. Run Steam again and see if you can launch Armored Core VI: Fires of Rubicon then.

If you can launch Armored Core VI: Fires of Rubicon after disabling the firewall temporarily, turn it back on again, then please go to fix #3.1 to see how to add Steam as a firewall exception so you can run the game.

If your Armored Core VI: Fires of Rubicon still refuses to launch, please move on to the fix #4 to see how to change your other network settings.

3.1 Add Steam to your firewall exception

If Armored Core VI: Fires of Rubicon can launch when you disable your Windows firewall for the time being, then your firewall should be stopping your computer from talking to Steam’s server, so you’ll need to add Steam as an exception. To do so:

1. On your keyboard, press the Windows logo + R keys simultaneously to open the Run box.
2. Type control firewall.cpl and hit Enter.
   
   
3. From the left navigation pane, click Allow an app or feature through Windows Defender Firewall.
   
   
4. Scroll down and check if Steam is on the list. If it isn’t, proceed to add it to the exception list.
5. Click on the Change settings button.
   
   
6. Click Allow another app….
   
   
7. Click Browse… and go to the installation folder for Steam.
   
   
   
   If you don’t know what the installation folder is for your Steam, simply right-click on its shortcut and select Open file location.
   
   
8. Find steam.exe and click on it. Then click Open.
   
   
9. When it’s located, click Add.
   
10. Now make sure Steam is added to the list and tick Domain, Private, and Public. Once you’re done, click OK.

Now open Steam and try to launch Armored Core VI: Fires of Rubicon again. If the game still refuses to launch, try the next fix below.

4. Change your DNS server

Default DNS servers provided by your ISP (Internet Service Provider) could fluctuate at some point of the day, or they could be too far away from the game servers, thus with the Armored Core VI: Fires of Rubicon’s launching problem. To make sure that your DNS server is not the culprit to the game’s launching problem, you can first flush your DNS cache and then switch to a public DNS server.

To do so:

4.1 Flush your DNS

By flushing your DNS, your DNS cache will be cleared. So when your PC needs to access the internet, it’ll need to obtain the address from the DNS server again (and we’ll change the DNS server address later). This may solve the Armored Core VI: Fires of Rubicon not launching problem if the DNS cache data is invalid or corrupt. Here’s how you can flush the DNS:

1. Press the Windows logo key and R on your keyboard.
2. Type cmd, then press Shift and Enter at the same time to run Command Prompt as administrator. If prompted for permission, click Yes.
   
3. Copy ipconfig /flushdns, and paste it in the pop-up window. Then press Enter.
   
4. Your DNS cache is successfully cleared.
   

4.2 Switch to a public DNS server

Then switch to a public DNS server (like the Google DNS server in the example below, since it’s fast and secure):

1. On your taskbar, right-click the network icon, then click Open Network & Internet settings.
   
2. Click Change adapter options.
   
3. Right-click the network you’re using, then click Properties.
   
4. Select Internet Protocol Version 4 (TCP/IPv4), then click Properties.
   
5. Select Use the following DNS server addresses, fill in the Google DNS server addresses as below, then click OK.
   
   Preferred DNS server: 8.8.8.8
   Alternate DNS server: 8.8.4.4
   
   
6. Then run Steam and try to launch Armored Core VI: Fires of Rubicon again to see if the problem is fixed. If the problem still remains, please move on.

5. Disable conflicting software

Steam can be quite sensitive about certain programs running in the background, especially the ones that occupy network resources. Here’s a list of such programs that you need to pay extra attention to:

• NZXT CAM
• MSI Afterburner
• Razer Cortex
• Anti-virus or anti-spyware software (some mentioned Norton Security stopped Armored Core VI: Fires of Rubicon from launching)
• VPN, proxy, or other firewall and security software (some mentioned NordVPN)
• P2P or file-sharing software
• IP filtering or blocking software
• Download manager programs

If you have none of the above-mentioned suspicious software programs installed, but your Claunch Armored Core VI: Fires of Rubicon still refuses to launch, you may need to perform a clean boot in Windows to see if the problem remains there.

If launch Armored Core VI: Fires of Rubicon launches well when you do a clean boot, one or more third-party services or programs are interfering with the game, so you will need to disable 3rd-party software one by one until you find the culprit, either remove it or update it to see if it helps.

6. Disable overlays

According to some users, disabling in-game overlays helps to fix the Armored Core VI: Fires of Rubicon launching problem, so you may also try to disable the overlays. You can do so on Steam or GeForce Experience:

On Steam

1. Open your Steam and go to the Library tab.
   
2. Right-click launch Armored Core VI: Fires of Rubicon from the game list and click Properties.

1. Run GeForce Experience.
