A computer is a great thing – when it works. However, sometimes out of nowhere (no fault of your own), there are some problems or bugs, and you have no idea how to fix them.

Error “msvcr100.dll is missing” is one of those problems. It’s easy to fix, and I’ll give you a few ways to do it.

DLL stands for Dynamic Link Library, and Windows has a lot of .dll files. This error occurs when programs executed by Visual C ++ needs a Microsoft Visual C ++ file, and for some reason, your system doesn’t have it anymore.


It would help if you tried to download the Visual C ++ package for your operating system.

This will replace the package you have on your computer, and nine times out of ten, it will restore the file.

However, nothing is predictable with a computer, so let’s say it doesn’t. The file is missing or damaged, so you have to replace or restore the file yourself. You can get the file off the Internet, but be sure before that it’s a secure website.

Some websites have older or even damaged files. A secure website that you can trust is.

It’s a straightforward website. When you reach the homepage, there is a line of white text about halfway down the page. Click M for msvcr100.dll.


The white text’s right is a search box where you can enter a filename if you want to do it.


You will then come to a page where you can download the file. Look on the right side of the page, and you’ll see a long gray rectangular box; It will have “Manual Fix” in the upper left corner. This is a free download and will be in .zip format. At the bottom is a large button labeled “Download ZIP-File.” Click it.


After clicking “Download Zip files”, a box will appear asking what operating system (32-bit or 64-bit) you have as well as the file version. Choose your operating system, the latest file version, and click on it. When you do, a small download box will appear. Click on it to load your file.

After you click Download, a dialog box will pop up. Select the option “Open with” to open the file.

Note: you’ll need a zip program for this sequel; I use WinZip. For this article, that’s what I will use for the screenshots.

When you click “Open with” you will be presented with an open WinZip box containing the file and a readme.txt file (which you can ignore). Click the file “msvcr100.dll” to highlight it, and then click “Extract to”.


When you click on the “Extract to” button, you will take the msvcr100.dll file and place it where it is supposed to be on your computer. In this case, please unzip your file to the folder “C: Windows System32” and copy it to the file “C: Windows SysWOW64” (if you have a 64-bit system) to add the file to your computer.

Now you have replaced/restored the msvcr100.dll file, and all should be true to the world. If you’re still having problems, boot into Safe Mode and do a full scan for malware/viruses.
