digitalmars.D.learn - How to link a msvcr120.dll in an inverse recursive way after a Windows

**Folder structure**

.\msvcr120.dll
.\folder1\HelloWorld.exe
.\folder2\HelloWorld.exe



Microsoft Compiler Runtime DLL
As you might know that a basic D Language example 
`HelloWorld.exe` requires `msvcr120.dll` to work.



**To not include** `msvcr120.dll` into every `.exe` executable's 
`.\folder\` **and to not marginally increase the overall size of 
the project**: I'd like to link every `.\folder\.exe` binary to 
the `.\msvcr120.dll` dynamic library.

**Notice**
Launching the `.exe` binary with external script to change the 
`path` variable is not a solution.
I'd like the `.exe` binary to "know" and try to search for 
`.\msvcr120.dll` by itself after clicking it to launch.

I've been reading up fairly recently on RPATH for *nix which does what 
you want. Unfortunately as far as I've found there is no way to do this 
on Windows without an extra executable.

You don't need to do this. msvcr120.dll is already shipped with 
the DMD compiler at 
[DMD-install-folder]\windows\bin64\msvcr120.dll. (It is also in 
[DMD-install-folder]\windows\bin). You can access it directly 
from there.

When you run your EXE... the OS looks for the DLL in the same 
folder of the EXE- if it cannot find it it looks in the folders 
specified in your PATH.

You can test if this is the case by executing 'where 
msvcr120.dll' at a DOS console command prompt. If the DLL is 
reachable in any folder in your PATH environment variable these 
specific path(s) will be displayed. In this case you don't need 
to do anything - the EXE should be able to run and load the DLL.

The fact that you get this error indicate this is not the case. 
You can do 1 of the following 2 things:
- add your DMD bin64 (or bin) path to the PATH environment 
variable.
--or--
- Copy the DLL to C:\Windows\System32\ - that will for sure 
already be in your PATH so you don't need to modify your PATH 
environment variable.

The problem is, D Language Compiler is not included along the 
Windows Operating System.
Neither msvcr120.dll is included along the Windows Operating 
System.
You have to download it. No other way.

How can you download it, if your .exe binary that has the 
functionality to download it, cannot even be started due to 
msvcr120.dll not existing on the operating system.

You can try to use pre-existing Command Line Utilities like 
bitsadmin (Windows 7), curl (Windows 10), but really how can you 
interact with them from within D Language Binary if it can't even 
launch.

You can try to write a batch script for all that.

I really do not want to write batch scripts for the rest of my 
life,
that's why I'm here in the D Language Forum.


 Copy the DLL to C:\Windows\System32\


It required administrator privilegies and this is only a 
HelloWorld example
of the D language deployed on computers, where the D language is 
yet to be installed.

No compiler is included natively with the Windows OS. Not even 
Microsoft's.

Or... you download the DMD installer which conveniently include 
it for you.

I don't understand this. You need DMD to build your EXE. I 
suppose you have this since your question is specifically about 
DMD. If that is the case you have the DLL you need.

True. In that case just distribute the DLL (taken from the DMD 
bin folder) alongside the HelloWorld EXE so that both reside in 
the same folder on the target computer. If you don't have 
administrative priveleges you cannot modify the PATH on the 
target computer either, so this is the only way. That is anyway 
quite standard under Windows - if you search for msvcr*.dll on 
any Windows machine you'll find lots of copies co-located with 
the EXEs that use them (using the version that came with the 
specific version of Visual Studio they were using to build the 
EXE - for example msvcr90.dll). These DLLs are simply the Visual 
Studio C/C++ Runtime distributed with Visual Studio.

The proper way to do this is to ship the correct version of the 
Visual C++ redistributable installer and run it as part of the 
application install process:

Sure. But the OP seems to indicate that he doesn't have 
administrative privileges on the machines they wish to distribute 
and test his HelloWorld example.

I don't know if you can run an installer without administrative 
privileges - at least not if you want to write to Program Files / 
Program Files (x86), modify the Registry, environment variables, 
etc.  I'm not even sure if you can create a folder on Windows 10 
without administrative rights without resorting to some tricks. 
I've never required that - and would think that the IT department 
(that handles installs and updates on their organization's 
computers) should have an admin account on all of them.

My take was that he can simply copy the EXE and associated DLLs 
to an existing folder on the target machine if he just want to 
test it running on a non-developer machine.

Making an installer is another mini-project by itself .. not sure 
if he wants to be burdened with such a step simply to resolve his 
DMD issue.

But your redistributable installer link is indeed the proper way.
