Hi, I'm new to Wolfram. I downloaded yesterday Wolfram Engine 12.0 and tried to call it from my .net app in C# but I ended up with error where it asked me to choose a Mathlink program to launch. the error in my program raise at this point : `IKernelLink ml = MathLinkFactory.CreateKernelLink();` can someone advice on what is missing here. thanks in advance. ps : I using `Wolfram.NETLink.dll` and `ml32i4.dll`

I think you need to specify the location of 'wolfram.exe': https://reference.wolfram.com/language/NETLink/ref/net/Wolfram.NETLink.MathLinkFactory.CreateKernelLink_overload_3.html With the Wolfram Engine in the default installation location it would be: "c:/program files/wolfram research/wolfram engine/12.0/wolfram.exe" (I didn't try this, but I think this is the direction to look into)

Don't look further, the answer is: The developer comments that the ml32i4.dll file is missing from the NETLink directory since version 12.1. Please find the dll file in link below. If you put an ml32i4.dll file in there, next to the existing ml64i4.dll file, things will work. https://amoeba.wolfram.com/index.php/s/R27S4gdL9WxcnnE
