I need to run a small program in the Windows Preinstallation Environment, my program works fine on v7 & v10, but crashes on v8.1. Windows 8.1 ISO: https://www.microsoft.com/en-us/software-download/windows8 On the Windows Installer window, I press Shift+F10 to open CMD, then I run the program from there. Here is the example code, I'm using Delphi 11.3 CE: program Project3; {$APPTYPE CONSOLE} {$R *.res} uses System.SysUtils; begin WriteLn('Test'); ReadLn; end. Here is the result if SysUtils is included: Here is the result if SysUtils is not included, so I suspect the problem comes from the SysUtils unit. I'm new to Delphi recently and don't have the ability to debug in this case. Please help, thanks for everything.

I compiled the program in the Debug configuration with the Optimization option turned off but the problem persists. Update: I installed and compiled the program with Delphi 10.4.2 and everything works as expected.

@programmerdelphi2kI see what you mean, this operating system is not full of components. But a lot of applications can run on this environment. The confusing thing is that my program can run on WinPE 7 and WinPE 10 but not on WinPE 8.1. The error given in my opinion is not related to missing components.
