Hi. The link you provided is invalid (is your repository private?), but I'll try my best to help. This is a problem with your system being unable to locate "msvcr100.dll", which it needs to load for your application. From what I have found from a quick search, this .dll is a part of Microsoft Visual C++. You should try installing Visual C++ and see if that solves the problem.

Best

Did you try compiling with LDC?
Their Windows support is better maintained.

Anyhow, so what's happening is that dmd by default uses the digitalmars C runtime (32-bit only) whereas dub will use the llvm linker (64-bit) by default. Now llvm's linker searches for the Microsoft C runtime and can't find it. Hence, the error which you're receiving.

You won't need Visual Studio for this, but something which ships msvcr100.dll.
So sth. like this should be enough:

https://www.microsoft.com/en-us/download/details.aspx?id=5555

BTW if you prefer using optlink and the  digitalmars C runtime, you can instruct dub to do so with: --arch=x86

even when i installed the latest vcredist_x86 it doesn't work, but using --arch=x86 it works,   but only when i don't include dlangui in the dub.json, it give me another error https://i.imgur.com/f1Rvlg1.png (app.d line 21 "code = stdin.readln();" and line 7 is "void main(string[] arguments)"), so i maybe need to find a new gui library, and thanks now at least i can compile.

You don't need the *latest* VC runtime (2019), but 2010, i.e., Seb's link. For DMD that is, LDC should be fine with the latest one.

I got into this recently too.
I have the latest VS and redistributable packages installed and was unable to find msvcr100.dll too. Which is very odd.
Lucky I found it on another software installed on my PC.

"dflags":	[
	"--arch=x86"
]

This should work. Didnt tried though
