The clear answer to "This app can't run on your PC" is that the program is incompatible with the system version, hardware configuration, or software architecture. Solutions include: 1. Check the system type and enable the WoW64 compatibility layer; 2. Run the program as an administrator and select the appropriate compatibility mode; 3. Check and install the required Windows features or components such as .NET Framework, Visual C Redistributable, or DirectX runtime library.

This prompt is actually quite common, especially when you try to run an incompatible program. "This app can't run on your PC" usually appears because your computer system version, hardware configuration, or software architecture is incompatible with the application. The core of solving this problem is to figure out which aspects are wrong and make corresponding adjustments.

1. Confirm whether the system architecture matches (32-bit vs 64-bit)

Windows 10 has two versions: 32-bit and 64-bit versions, while some old programs only support 32-bit architecture. If you are using a 64-bit system, you may encounter situations that cannot be run.

• Open Settings → System → About to view "System Type" under "Device Specifications"
• If it is a 64-bit system, you can try to enable the "WoW64 (Windows-on-Windows 64)" compatibility layer
• In addition, some installation packages themselves are targeted at legacy systems, such as XP or Vista, and may need to run in compatible mode

You can right-click Programs → Properties → Compatibility → Check "Run as Administrator" and select the appropriate compatibility mode to try it.

2. Check whether the system version meets the requirements

Sometimes it's not that the program is too old, but that it needs updated Windows features or components. For example, some newer games or development tools require a specific version of the .NET Framework, Visual C Redistributable, or DirectX runtime library.

• Make sure your Windows has been updated to the latest status (Settings → Update & Security → Windows Update)
• Check the official program website instructions to see if there are minimum system version requirements (such as Win10 20H2 or Win10 21H2)
• Install missing runtime libraries, such as VC runtime collection or .NET Framework 3.5/4.x

If you are not sure what is missing, you can try manually installing the latest VC runtime package, which many programs rely on.

3. Turn off antivirus software or system policy restrictions

Sometimes it is not because of the program itself, but because it is blocked from running by Windows Defender or other third-party antivirus software.

• Temporarily turn off Windows Defender real-time protection (Settings → Privacy and Security → Windows Security Center → Virus Protection)
• Or temporarily exit other antivirus software and try to run the program
• If you are a company computer, it may also be caused by group policy restrictions, and it will be difficult for ordinary users to modify this part of the content.

Although this situation is rare, if you are sure that the program is safe, you might as well try these methods.

Basically, these common causes and corresponding solutions. Most of the problems are focused on compatibility and system configuration, and they can be solved without too complicated operations. However, remember one thing: not all programs can run smoothly on Windows 10, especially very old software, which may require a virtual machine or a compatible system to run.
