How to fix msvcr100.dll is missing in Visual Studio 2017

I recently started working on a project related with app development in Visual Studio 2017, which is why I downloaded and installed Visual Studio 2017 on my system. I got the following message when I attempted to launch it: The program can’t start because msvcr100.dll is missing from your computer. Try reinstalling the program to fix this problem. I tried installing different versions of Visual Studio, however nothing seemed to work. Funny enough, the program worked when I installed it on my laptop. Anyway, my laptop is too out-dated to work well with Visual Studio 2016. I discovered a lot of fascinating information when I went online to search for a solution.


The first thing I discovered is that the msvcr100.dll is missing error is fairly common and a lot of users experience it not just in Visual Studio. I also discovered that the error was caused by the fact that Microsoft Visual C++ 2012 wasn’t installed in the course of installation, probably because an anti-virus software blocked it. There are different ways to fix this error, but I decided to go for the easiest method. All I did was to download the dll library from After the download, I used my anti-virus to scan it to be sure it’s not a malware. I also confirmed that hash and md5 sum were original msvcr100.dll library. The next thing I did was to install the library using the instructions on the website, after which I rebooted my system. After doing this, I stopped getting the msvcr100.dll is missing error message, and Visual Studio 2017 worked perfectly on my Windows 10.
