Can I run an external application from UE4 build?

I have zero experience with this, but FPlatformProcess::CreateProc might be what you’re looking for.

Edit:

FPlatformProcess::CreateProc(TEXT(“C:\Users\\Desktop\Test.exe”), nullptr, true, false, false, nullptr, 0, nullptr, nullptr);

Used that in my code and it worked as expected. Would be nice to have an overload that only required the first parameter, but I’m really happy that it worked so intuitively.

It seems that FPlatformProcess is for Windows only. There’s also FGenericPlatformProcess that works for other platforms, but uses untested code.

Hi it works perfectly but ive written it in a C++ Actor script inside the BeginPlay() function. And it opens two windows of my executable. Can you tell me the possible reasons for this? I am very new to Unreal.
