Don't let DLL errors stop you. We cover the root causes and proven fixes for the MSVCR100.dll missing in Windows 11, ensuring you can safely solve the Windows 11 MSVCR100.dll missing issue without harming your system.
Missing MSVCR100.dll - nothing works. I need help
It all started with me just wanting to watch a movie through VLC for the first time on my computer. And now I can't even move files to certain folders because I am not an admin. I tried making myself an admin, but the PC won't allow me to.
I watched a lot of videos on this, but this file is not missing on my PC. I tried to replace the file in system32 and sysWOW64. So the files are not missing. I am so lost. Please help

When you see the error in Windows 11: System Error. The program can’t start because MSVCR100.dll is missing from your computer. Try reinstalling the program to fix this problem. You might be lost. What’s the MSVCR100.dll file? Why is it missing? It will stop you from opening your programs.
This guide will show you everything about the MSVCR100.dll file, and walk you through safe, step-by-step fixes. Let's get that program running.
In fact, a program you’re trying to run is asking Windows 11 for a specific piece of shared code—a Dynamic Link Library (DLL) file named MSVCR100.dll. Windows can’t find it where it’s supposed to be, so it shows you the error. It signals a broken link between your modern operating system and the foundational code many applications rely on.
Several culprits can trigger the MSVCR100.dll is missing messagein Windows 11.
Understanding the root cause helps you pick the right fix.
Let’s explain what they are. The files MSVCR100.dll and MSVCP100.dll are not native components of the Windows operating system. Instead, they are essential parts of the Microsoft Visual C++ 2010 Redistributable package. This package provides a standardized collection of common code that many applications rely on to run.
Developers who create software using the Microsoft Visual C++ 2010 programming tools use this package to avoid embedding redundant basic functions directly into their programs, which would result in excessively large and inefficient installations. Consequently, these applications are built to depend on the shared MSVCR100.dll (which handles core C runtime functions) and MSVCP100.dll (which manages C++ standard library functions) files.
For any software that requires them, these shared files must be correctly installed and accessible on your system for the program to operate.
Here are some proven solutions for you to fix the missing MSVCR100.dll problem.
Never underestimate the power of a fresh start. Simply close the error box and the program completely. Then, give your whole system a reboot. This clears the system’s memory (RAM) and stops any temporary processes that might be interfering with the file’s access. It’s a quick, zero-risk step that can resolve glitches where the file is actually present but something in the software’s current state just isn’t seeing it.
Sometimes, it’s a permissions issue. The application might need elevated privileges to access or call upon certain system files. Find the program’s shortcut, .exe file, or search it from the start search box, right-click on it, and select "Run as administrator".
If this works, you can permanently set the program to always run with admin rights by right-clicking its shortcut, going to Properties > Compatibility, and checking "Run this program as an administrator".
Windows includes a handy troubleshooter for general program compatibility. Fix it using the steps below:
1. Go to Settings > System > Troubleshoot > Other troubleshooters.
2. Look for "Program Compatibility Troubleshooter" and run it.
3. This wizard will let you select the program that’s failing, and it will automatically try to detect and apply compatibility settings or suggest known fixes.
It can sometimes reconfigure the environment so the program finds the DLLs it needs.
Besides, you can also install the complete, official Microsoft Visual C++ 2010 Redistributable package (both x86 and x64 versions) from Microsoft instead of downloading MSVCR100.dll for Windows 11 individually. This ensures all related files are installed correctly and registered in the system, eliminating the Windows 11 MSVCR100.dll missing error properly.
The cleanest fix is often to repair or reinstall the correct Redistributable package.
1. Go to your Windows Settings > Apps > Installed apps.
2. In the search bar, type "Microsoft Visual C++". You’ll likely see a long list from different years.
3. Look for the "Microsoft Visual C++ 2010 Redistributable" entries (both x86 and x64).
4. For each one, click the three dots (…) and select "Modify".
5. In the setup window that appears, choose the "Repair" option.
Follow the prompts. This process replaces any missing or corrupted files with fresh, official ones. After repairing both the 2010 packages, restart your computer and try your application again.
If the error is more systemic, a built-in Windows utility called System File Checker (SFC) can be a lifesaver. It scans for and restores corrupted Windows system files.
1. To run it, right-click the Start button and select "Windows Terminal (Admin)" or "Command Prompt (Admin)".
2. In the window, type the command sfc /scannow and press Enter.
3. The scan will take a while. If it finds and fixes corruption, including issues with protected system-level files that might be interfering, it will report so.
Once it's complete, reboot your system. This isn't a direct fix for the redistributable, but it ensures Windows itself isn't part of the problem, clearing the way for other solutions to work.
If you’re worried about data loss once you meet the MSVCR100.dll issues while using photo editing software or a database program, this is where a dedicated recovery tool like MyRecover can help salvage unsaved or lost documents from the chaos.
1. Download and install MyRecover on your Windows 11 computer.
2. Run the installer with administrative privileges to ensure it sets up correctly on your Windows 11 PC.
3. Tap Deleted Files Recovery, choose the hard drive where the crashing app was installed, and click Scan while pointing at it. Wait for it to complete, and hit OK.
4. Preview and select the files you need, and hit Recover.
5. Choose a destination to save these recovered files.
What does the MSVCR100.dll file actually do?
A: It's a shared code library for the Microsoft Visual C++ 2010 runtime. It contains standard functions for tasks like math and memory management. Developers use it so they don't have to rewrite this common code, making apps smaller and more efficient. The error means a program needs this shared "toolbox", but Windows can't find it.
Is it safe to download MSVCR100.dll from a DLL website?
A: No, it is strongly discouraged and generally unsafe. Files from these sites may be incorrect, outdated, or contain malware. They also rarely fix the core issue. The only safe method is to install the official Microsoft Visual C++ 2010 Redistributable package from Microsoft or a trusted installer.
Why did I suddenly get this error on Windows 11 when the software worked before?
A: A sudden error usually means a recent system change corrupted or removed the required file. Common triggers are a Windows Update, installing a new program that conflicts with or overwrites the runtime, or occasionally malware or a cleanup tool. The error indicates a broken link in your system's software environment.
How do I know if I need the x86 or x64 version of the Visual C++ Redistributable?
A: Install both. Windows 11 is 64-bit and uses the x64 version for 64-bit apps. However, it runs 32-bit (x86) apps through a compatibility layer, and those apps require the x86 runtime files. Installing both vcredist_x86.exe and vcredist_x64.exe ensures compatibility with all software.
Can I just copy the MSVCR100.dll file from another computer?
A: Technically possible, but not recommended. While copying from a similar system might work temporarily, it's an unstable fix. It doesn't install the full runtime environment, can cause version conflicts, and may be reversed by updates. Installing the complete official package is the proper, long-term solution.
What should I do if none of these fixes work for the MSVCR100.dll is missing error?
A: First, check the software developer's site for patches or known compatibility issues. Second, perform a Windows "clean boot" to rule out a conflict with another program. If the app works in a clean boot, another installed application is interfering. Finally, as a last resort, try running the program in Compatibility Mode for an older Windows version.
