Downloading and Installing Essential C++ Redistributables

Some games and applications that were developed using Visual Studio C++ require certain runtime libraries to run smoothly. Therefore, it is essential for every gamer and user to download and install all the essential C++ redistributables so that there is no chance of any error related to C++ runtime libraries.

Before downloading and installing any C++ redistributables, you must check which ones you already have and the needed ones that you must download and install from the Official Microsoft Redistributables page. However, you can also download an AIO setup from any third-party website that will automatically install all the required redistributables.

But it is recommended to install all the required redistributables from Microsoft’s Official Website to avoid any chances of malware entering your PC.

Disable Overlays

Overlays can also be a reason for errors such as Armored Core VI: Fires of Rubicon Application Error 0xc0000005 to occur because they might interrupt the game’s process, causing it to crash. Overlays provide a number of useful features during gameplay, such as screen recording, instant replay, fps counter, etc. But even then, they can be a cause of stutter, lag, and crashes.

Therefore, it is recommended to try turning off any overlays if you’re getting any unexpected crashes, lag, or stutter. You can check out our complete guide on how to turn off any and all application overlays. However, in this guide, I’ll guide you about Steam, Discord, Xbox Game Bar, and Nvidia Geforce Experience Overlays. Here’s how you can Disable these overlays.

Disable Overclocking

Overclocking your graphics card can give you a certain boost in some situations, but it can cause much more disaster because it can cause your graphics card to consume more voltage, which can result in overheating, making the card exceed its heat limit and causing its components to get damaged and become unstable.

Moreover, overclocking a graphics card voids the warranty of the card provided by its manufacturing company or the supplier. Therefore, keeping these circumstances in mind, it is recommended not to overclock your graphics card and keep the clock speed at a stable limit.

However, these are some steps to follow to keep your graphics card at a stable limit by Disabling Overclocking.

For Nvidia

1. Press the Alt+Z keys, and the Nvidia Geforce Experience overlay will appear.
2. Now click the Performance button on the top left, and the Performance options tab will appear.
3. Then click the reset button to restore default settings, which will disable any applied overclocking.

For AMD

1. Open the AMD software and go to the performance settings section.
2. Then click the tuning section to open its settings and enable the manual control.
3. Now, you can change the tunings according to your requirements, but it is recommended to keep them underclocked to disable overclocking.

MSI Afterburner

1. Using MSI Afterburner to disable overclocking is very easy; just open the MSI Afterburner application.
2. Now, in the sliders, just slide down your core clock and memory clock sliders, and you’re good to go.

   

Increase Your Virtual Memory

Virtual Memory/Paging file can be very helpful in running your system smoothly and efficiently if you are experiencing any memory-related issues like Armored Core VI: Fires of Rubicon Application Error 0xc0000005 while running some intense memory-draining apps or games such as Armored Core VI: Fires of Rubicon.

Virtual Memory is basically a reserved space on your HDD or SSD that acts as RAM when your system’s physical RAM is completely utilized by some other process or processes. Therefore, it can be beneficial to increase your virtual memory to a reasonable amount to get rid of errors such as Armored Core VI: Fires of Rubicon Application Error 0xc0000005 while not using a large amount of precious space as memory.

However, you can follow the steps below to increase your virtual memory, but make sure to increase it just about a reasonable amount.

1. Open This PC and right-click anywhere.
2. Then click Properties to open system properties.

4. Now, in the opened window, click the Settings… button under performance to open Performance options.

   

5. In Performance options, open the Advanced tab and click the Change… button under Virtual Memory.

   

6. Once the Virtual Memory settings open, uncheck the Automatically manage paging file size for all drives
   check box.

   

7. Finally, select any drive and enter the Initial size and Maximum size after enabling the Custom size option and click Set to apply.

   

Add Exception in Data Execution Prevention (DEP)

Data Execution Prevention, also known as DEP, is a security-based technology built in the Microfot Windows system to prevent the execution of unknown executable code from places where it isn’t supposed to be. Moreover, it also protects your system against different types of viruses, malware, and certain system vulnerabilities that might occur.

However, it can also be the cause of Armored Core VI: Fires of Rubicon Application Error 0xc0000005 to occur as it may possibly be detected as malware. Therefore, we can add Armored Core VI to the Exception list of DEP to make sure that DEP is not the cause of this error.

Here’s how you can add an exception to the DEP.

1. Open system properties by right-clicking in This PC and selecting Properties.

   

2. In the system properties, click Advanced system settings.

   

3. After that, click the settings button under performance in the advanced tab.

   

4. Then open the Data Execution Prevention tab in the performance options window and choose the Turn on DEP for all programs and services except those I select.

   

5. Now click the Add… button and add the Armored Core VI to the exclusions list.
