Starting with version v4.2.18, SmartSDR for Windows now supports x64 or ARM processors, replacing legacy 32-bit support, aligning with modern Windows standards, and improving overall system efficiency.
When installing a new version of SmartSDR, there will be two options: one for the x64 version and one for the ARM64 version. You will need to select the correct version for your PC's processor architecture. The most common option is the x64 version.
But if you are unsure which version to download and install on your PC, here are a few quick ways to determine whether your PC is using an ARM or x64 processor:
Method 1: Windows Settings (preferred method)
- Open Settings
- Go to System → About
- Look for System type
- “64-bit operating system, x64-based processor” → x64
- “64-bit operating system, ARM-based processor” → ARM
Method 2: System Information
- Press Windows + R, type msinfo32, and press Enter
- In the System Summary, look at System Type
- “x64-based PC” → x64
- “ARM-based PC” → ARM
Method 3: Task Manager
- Press Ctrl + Shift + Esc
- Go to the Performance tab → select CPU
- The processor name will usually indicate the architecture
