Overview

When attempting to launch Counter-Strike 2, some players face a frustrating error with the code “0x0000045a”

The error message indicates that the launcher is unable to load module Engine 2, preventing the game from starting. Fortunately, the reason for this error is relatively simple, although the solution may not be ideal for everyone.

4 Solution Options

Here are the possible solutions to fix the CS2 error 0x0000045a and resolve the launcher crash:

1. Check CPU Compatibility

• Counter-Strike 2 requires your computer’s processor to support instructions SSE 4.1 and SSE 4.2.
• To determine if your CPU supports these instructions, use a utility like CPU-Z, which can provide a list of supported instructions.
• Unfortunately, some older CPUs, including certain AMD processors like Athlon, Phenom, and A6, do not support SSE 4.1 and 4.2.

2. Upgrade Your CPU

• If your CPU does not support SSE 4.1 and 4.2, the recommended solution is to upgrade your computer.
• Look for a processor that supports these instructions. Examples of compatible processors include AMD FX 8350 and Intel Xeon X 5680.
• Upgrading your CPU may require additional hardware changes and possibly a new motherboard.

3. Stay Informed About Updates

• Keep an eye on updates from Valve, the developer of CS2. While there may not be an immediate solution, Valve could release an update that removes the requirement for SSE 4.1 and 4.2 instructions.
• Valve has a history of updating their games, and since Dota 2 and CS2 now share the same engine, there is hope for future updates.

4. Consider Software and Hardware Updates

• Valve has made it clear that they will stop supporting outdated hardware and operating systems.
• CS2, for instance, may only run on a fresh build of Windows 10 or Windows 11 with version numbers 21H2 or 22H2.
• To continue playing CS2 and other modern games, you may need to consider both software and hardware upgrades to meet the system requirements.

System Compatibility Notes

It’s important to understand the compatibility of your system components with Counter-Strike 2:

CPU Compatibility

• Counter-Strike 2 requires SSE 4.1 and SSE 4.2 instructions.
• CPUs like AMD Athlon, Phenom, A6, and older Intel processors like q6600 do not support these instructions.
• Compatible CPUs include AMD FX 8350 and Intel Xeon X 5680.

Operating System Requirements

• Counter-Strike 2 may only run on Windows 10 or Windows 11 with version numbers 21H2 or 22H2.
