A core part of all computers (laptops or desktops) is the Central Processing Unit (CPU). In recent years, ARM-based CPUs have become more popular due to their power efficiency which makes them great for mobile devices like smartphones and laptops.

ARM-based CPUs are architecturally different from more traditional x86/x64 CPUs, in which all Sage desktop software applications were created for. 

This means that Sage software, for example Sage 50 Accounts, will not work on a computer which has an ARM based CPU. Some examples of ARM-based CPUs and devices are:

ARM Devices:

• HP OmniBook X
• Lenovo Yoga Slim 7x
• Dell XPS 13
• Microsoft Surface Laptop
• Microsoft Surface Pro 11
• Samsung Galaxy Book 4 Edge
• Acer Swift 14 AI
• HP EliteBook Ultra
• ASUS Vivibook S15

ARM CPUs:

• Qualcomm Snapdragon X Elite
• Qualcomm Snapdragon X Plus

 CAUTION: This is not an exhaustive list, more models are available. Please consult with your IT equipment supplier or follow the steps below to check if you have an ARM CPU.

How to check your CPU type

 NOTE: These steps are written for the Windows 11 Operating System

1. Click Start and then click Settings.
2. In the System section, scroll to the bottom of the list and click About.
3. Expand the Device Specifications section, and check the System type:
   
   You'll see either x64-based processor, x32-based processor or ARM-based processor.
4. If your processor is ARM-based, it isn't compatible with Sage desktop software.
