For the Download and more instructions, make sure to check out the installation instructions and download links below.
On rare occasions, the program is not recognizing the api-ms-win-crt-stdio-l1-1-0.dll, even though it is installed correctly. In these cases, the installation of the Microsoft Visual C++ Redistributable Package could help. If you are still getting the Missing Error, try installing it here.
Clearly this is solved by installing the Update for Universal C Runtime in Windows (KB2999226). I could check for the hotfix during the install script but all of the methods I've found to do this are either too slow or unreliable.
How can I prevent this error from occurring? Can I change my solution so that I don't require this dependency? Am I linking against something I can remove? Can I redistribute the hotfix along with my application?
Edit 2: I've tried copying all of the Universal C Runtime Library DLL's to the application directory since Microsoft now allows (but doesn't recommend) local mode installation of the UCRT. There are 41 files in C:\Program Files (x86)\Windows Kits\10\Redist\ucrt\DLLs\x64 and api-ms-win-crt-runtime-l1-1-0.dll is one of them. However, now running the application results in this error:
I've tried debugging the application with MSVS 2015 but got nowhere. I opened the executable in Dependency Walker and it appears that I'm missing similar DLLs listed in this answer, which says that Dependency Walker is old and this is a red herring.
You should link statically with the CRT. For a consumer application there are a lot of scenarios which result in particular DLL missing or its configuration botched. I was the installer technical lead for a very popular Windows application (thousands of installs per day) and you would not believe how common misconfigured Windows machines are out there. At the bottom I'll give a short list.
The universal CRT is a good idea but relatively new and it will be a while, (possibly a long while) until it being broken prevents your customers' PC from booting. That should be the threshold: If your customer cannot log in without DLL X then it is ok to depend on it.
Pretty important to keep in mind that this is not a hotfix. It is a normal update that is automatically delivered through Windows Update. So there's one fact you know, these machines are not being maintained. That's Very Bad News of course and having problems is to be expected.
It is an operating system DLL that is normally supplied along with the operating system install, starting with Win7. That ought to narrow down what's wrong with these machines, they are likely to boot XP. Small odds for Vista. XP is no longer maintained by Microsoft so seeing the update missing is not a coincidence.
That's fine but you need to double-check this in your installer and refuse to install on XP. Targeting XP is still possible, you have to change the Platform Toolset setting to "v140_xp". Not sure if that option is available in the Community edition, it would surprise me if it was.
Only one counts, ucrtbase.dll. The rest of them are the api-ms-win*.dll files that ought to be present in the Windows install directory. They are included so you can still get it going on XP and Vista, you should deploy these to c:\windows\system32 or c:\windows\syswow64, depending on the bitness. Do note that you documented the x64 directory, verifying that the user has a 64-bit version of Windows is another thing you have to double-check in your installer.
That is STATUS_DLL_INIT_FAILED, the DllMain() entrypoint of one of the DLLs you have a dependency on returned FALSE. Pretty bad news, not easy to debug and you certainly won't get anywhere trying to tackle this with VS2015 since it won't fail on your machine. You need to turn on loader snaps so the OS loader becomes chatty. Having access to a machine that has this problem is of course mandatory.
Yeah, time to cut your losses I'd say. Nobody can reasonably expect your app to work when they intentionally don't maintain their machine or refuse to update it. Verify in your installer that ucrtbase.dll is present and when it is not then just stop the install and tell them to update their machine first.
And I don't want the customer to having to install redist themselves, so I figured that cx_freeze include_msvcr option might be the way to go. However, even if I use include_msvcr option, the .exe is still not executable on windows without redist.
Compiled couple of .dll's using visual studio 2015, and tried to deploy on some older windows 7 / 64 bit. Tried also to guess which dll's are needed for application to start and copied MSVCP140.DLL & VCRUNTIME140.DLL - but application could not load vs2015 dll. Started to analyze what is wrong - and dependency walker showed dependencies from following dll's:
It mentions about release static libraries - so I thought that I could link against them and get rid from *L1-1-0.DLL* dependency hell, but no matter what I have tried - I had no success. I've tried to link against libvcruntime.lib, libucrt.lib, libcmt.lib, tried to disable using linker option "/nodefaultlib:vcruntime.lib", and even tried to add include directory $(UniversalCRT_IncludePath), and also overriding some of define's as I have tried to guess they works - none of my attempts helped.
Of course you will probably recommend to install Visual studio 2015 run-times, but one of our requirement is to support standalone executable - which works without any installation - so additional installation is out of question for now.
Note that the only other option is to compile with an older-compiler (like virus developers),not newer, because Microsoft promises same UCRT-requirements for any newer compiler-version as well.
I too was fighting with statically linking a solution with multiple components/project library dependencies importing functions from various parts of the MSVCRT, UCRT and Kernel. The hope was the resulting EXE could be just copied around where it was needed (it was no product which would justify a full MSI installation).
The Universal CRT is a component of the Windows operating system. It is included as a part of Windows 10, starting with the January Technical Preview, and it is available for older versions of the operating system via Windows Update.
So logically the only additional deployment dependency our C++ solutions add for the customer is the MSVCRT, because the UCRT should already be there on up-to-date/well maintained machines. Of course it adds a bit of uncertainty; you can't just copy the EXE and run on any machine, good or bad.
If you produce a decent deployment package like an MSI then it's straightforward to include when you have tools like WIX. Also to note is since the recent SDK you can include the 40-odd DLLs locally, but that doesn't satisfy the security update principle so I wouldn't do that.
This is really the only supported way to do it, see another example here. This article also suggests we link against "mincore_downlevel.lib" which is an important tip, crucial to whether you get these "api-ms-win*" missing DLL errors. For example:
It's also possible to statically compile ucrt library inside your application after which you will not need 43 dll's - but whether static link will for after linking or not - depends on your application - how many dll's and which api's are in use.Generally after ucrt gets linked into two different dll's they don't necessarily share same globals with each other - which can results in errors.
When troubleshooting linking problems - notice that unresolved __imp* function names from because of dllimport keyword usage - and if you link against libvcruntime.lib, you should not have any __imp* references.
The only thing you need to ensure is that you don't use any of its capabilities and Visual Studio automatically doesn't link to it. Ie. No asserts, no calls to anything in string.h or stdio.h, nothing. Anything the compiler can replace with its own intrinsics tho is ok, as are compiler checks like static_assert.
I've compiled a relatively simple Direct3D9 program in C++. However, whenever I try to use the Debug runtime, this error pops up. According to all of the references I have found, this DLL is not listed to exist in Windows 7. At first, I figured it was a problem with my application. But I went to Windows Update and installed all the latest updates.
