Ucrtbase.dll Error

[Kristeen Cheek]

Ive installed redistributable versions of various versions and whatever I could get a hold of and it still doesn't work. What am I missing? What is not included by default in Windows and Microsoft Visual C++ Redistributable for Visual Studio 2017?

Visual Studio 2017 will install the Windows SDK if you select components that require it. If you don't select to install any components that require the Windows SDK, the Windows SDK, will not be installed by Visual Studio 2017.

I would start, if you are the author of the program, by updating your solution to point to the correct version of ucrtbase.dll, and then install the Universal C Runtime on the system. If you are not the author, then I would install the Windows 10 SDK (26624), in order to resolve the faulting module.

I encountered this issue on two occasions where I was able to solve one of them and got the "problem area" of the other. This ucrtbase.dll error thing is just a general error. So what went wrong for me?

I have installed the Visual Studio 2015 and created Win32 project with some code. I compiled it successfully, but I can't launch exe file, because I don't have some ucrtbased.dll...So how can I solve it?

This problem is from VS 2015 silently failing to copy ucrtbased.dll (debug) and ucrtbase.dll (release) into the appropriate system folders during the installation of Visual Studio. (Or you did not select "Common Tools for Visual C++ 2015" during installation.) This is why reinstalling may help. However, reinstalling is an extreme measure... this can be fixed without a complete reinstall.

First, if you don't really care about the underlying problem and just want to get this one project working quickly, then here is a fast solution: just copy ucrtbased.dll from C:\Program Files (x86)\Windows Kits\10\bin\x86\ucrt\ucrtbased.dll (for 32bit debug) into your application's \debug directory alongside the executable. Then it WILL be found and the error will go away. But, this will only work for this one project.

A more permanent solution is to get ucrtbased.dll and ucrtbase.dll into the correct system folders. Now we could start copying these files into \Windows\System32 and \SysWOW64, and it might fix the problem. However, this isn't the best solution. There was a reason this failed in the first place, and forcing the use of specific .dll's this way could cause major problems.

The best solution is to open up the control panel --> Programs and Features --> Microsoft Visual Studio 2015 --> Modify. Then uncheck "Visual C++ --> Common Tools for Visual C++ 2015". Click Next, then and click Update, and after a few minutes, Common Tools should be uninstalled. Then repeat, but this time install the Common Tools. Make sure anti-virus is disabled, no other tasks are open, etc. and it should work. This is the best way to ensure that these files are copied exactly where they should be.

Why is ucrtbased.dll even needed?: Any DLL named "crt" is a "C-Run-Time" module or library. Microsoft explains them best. There are many variants of CRT today. They contain essential helper-code used by all Microsoft compiled executables, to "shim" or help your executable operate on the ever-growing number of OS versions and hardware. If the MSVC compiler is used, the relevant CRT DLL is linked automatically at compile-time. (If the DLL cannot be found at compile-time, then a linking error is generated.)

One way to not require the DLL, is to "statically-link" it to your project. This means that you essentially take the contents of ucrtbased.dll, and include it in your executable. Your file size will grow by approximately the size of ucrtbased.dll.

Incidentally, if you've ever run a MSVC program (usually from another individual, one of your old compiled programs from a previous OS version, or yours from a different machine) and it does not start, giving an error message of needing "Microsoft Visual C++ 20xx Redistributable" or "run-time" - then it means it can't find the needed *crt*.dll file. Installing that particular redistributable package (if known) will install the DLL, and allow the program to run... or at least get past that error and alert you of another missing DLL.

If you find yourself in this "DLL Hell" predicament, google "dependency walker" for an advanced tool to show which DLLs are still missing. This usually doesn't happen with professional software, simply because their (large, bundled) installers check for any missing dependent libraries (including CRT) and installs them first.

I would like to suggest additional solution to fix this issue. So, I recommend to reinstall/install the latest Windows SDK. In my case it has helped me to fix the issue when using Qt with MSVC compiler to debug a program.

A lot of people encounter the ucrtbase dll application crashing error on Windows. What is ucrtbase.dll? How to fix its related errors? Now, you come to the right place. This post of MiniTool will explain them in detail.

How to determine if ucrtbase dll is safe for the Windows system? Usually, the file is located in the C:WindowsSystem32 directory and the known file size on Windows is about 1,181,208 bytes. However, if the ucrtbase dll file is not in its original location, then we recommend you perform a virus scan to check its safety.

As mentioned above, ucrtbased dll is an important Windows system file. Once the file is missing or corrupted, you may encounter various application crashing issues. To repair the system files, you can run an SFC scan.

Step 2. In the elevated Command Prompt, type sfc /scannow command and hit Enter. After that, this tool will scan and repair the corrupted system files. This process may take you some time and make sure that it completes.

We found it to be a issue with the computer I'm using the DLLS are on a protected network that when i wasn't connected to my work network premiere couldn't access it. Now as long as I'm VPNed into my work network it will work.

This a common error occurs when you try running program or game and to run them the file ucrtbase.dll is missing. There is a different solution to the error as it occurs due to different reasons. It is one of the DLL file associated with Microsoft Visual C++ and to fix ucrtbase.dll try below 3-steps:

to keep you informed: I still have the same Problem with Windows 7 x64 Professional Clients on HP Workstations. Changing of Motherboards is not an option to me. I opened a supportcase and the problem is actually processed through the Autodesk development department.

Did you get a report #, case #, or defect # when you submitted this? Firmware and driver updates might be worth looking into, but I cannot suggest you flash anything in an official sense. That being said, if there are driver problems with the hardware there isn't much that can be done on this end. Do you have better luck with different hard drives? Thanks for any additional information.

yes, I got a case number. I send it to you by PM. I opened the case in last September. I know from a member in the german part of the forum (Tarek_K) that the case is being processed by the development department. At the moment, the solution of this problem is not time depending for me. I probably stay on 3ds max 2016 at least for the next half year. With that version I don't get the error on the same clients. The machines where the problem occured have been installed new with latest os and graphiccard updates. I didn't check what happens with different hard drives installed. I'll give this a try as soon as possible.

Are you having a freeze on startup and/or disk utilization error in addition to the crash on close? I read over your case but there's no mention of the disk utilization or startup crashes there. It's no problem but I may split these past few posts out to a new thread since they don't seem to align 1:1. The good news is that I don't think your motherboard is the problem here, from what I'm reading in your case log.

I can see that there's no update to the case in the past couple months. My thinking is that I need to put more information in there. I did find your thread here. I wonder if I should relog this for you with a slightly different title. If there is any other relevant information that would be great, and after reading more about your case I don't think it's the same issue that @Anonymous was having. Please correct me if I'm wrong.

All that being said, the UCRTBASE.DLL issues were mostly limited to W10. It's strange to see them in W7. I did a search for other issues like this and apparently some applications may replace that .dll with other versions, which does seem to be related to some problems I'm seeing. Are there any other adverse effects other than the crash on close I should be aware of?

I had only the appcrash error message on closure of 3ds Max 2017 using the German Language Version. There were no other problems. I took part of this thread because it was the only one I found, that also had a appcrash error caused by the module ucrtbase.dll. Meanwhile I also do think this it is related to some other issue than rayshawnpaul had.

I am not the only one that could reproduce the error message on Windows 7 Clients. In the german part of the Board matthias.schindler reported the same error behavior on Windows 7 Professional SP1 (Post 19). tobias.wiesendanger reported the same error behavior on Windows 10 (Post 37) and got them also on Windows 7 (Post 57). Matthias.schindler had no error on Win 8.1 Professional.

Thank you for the detailed information. This helps a lot. I had to edit the titles of the posts to match the thread title so this thread was easier to find for other people and I moved the posts to this new thread first so that if a solution is found it could be marked. Thanks for your understanding there.
