Avoiding the MSVCR100.dll or MSVCR100D.dll is missing error
MSVCR100.dll
This msvcr100.dll is the Microsoft Visual C++ Redistributable dll that is needed for projects built with Visual Studio 2010. The dll letters spell this out.
MS = Microsoft
V = Visual
C = C++
R = Redistributable
If you create a C++ project in Visual Studio 2010, this file is probably needed.
MSVCR100D.dll
The MSVCR100D.dll is almost the exact same file only the D at the end stands for Debug. This file has debugging enabled.
Why the error?
Ok, so recently I switched to Visual Studio 2010. I had a C++ application that worked perfectly in Visual Studio 2008. Once I compiled it with Visual Studio 2010 and ran it on a clean 2008 server (fully patched but otherwise clean), it failed to run with the following error.
TestWin32.exe – System Error
The program can’t start because MSVCR100.dll is missing from your computer. Try reinstalling the program to fix this problem.
Here is the screen shot:
The same things happens with the debug version of the file, only it is a the debug version of the same DLL as noted by the fact that the DLL name ends with D.
Autorun – System Error
The program can’t start because MSVCR100.dll is missing from your computer. Try reinstalling the program to fix this problem.
The screen shot is identical except for the D in the dll name.
I create a new project in Visual Studio 2010 using the project type of C++ Win32 Project and without making a single change to the default project, I built the file and tested it on my clean machine and the same issue occurred.
So obviously that is not acceptable. It seems like this should just not happen by default, but unfortunately it does.
Solution
It was actually really easy to resolve for my one project.
Here is what I did.
You can solve this any of the following ways:
- Statically link to the dll files so they are compiled into my executable instead of referenced as separate dll files.
- Included the dll in the same directory as the exe (I actually didn’t try this but I assume it would work).
- Forced everyone to install the VC++ Runtime Redistributable before running the app.
The first option seems the most stable and robust and easiest for a single executable. So that is the one I am going to use.
The second option doesn’t really make sense to me and I would probably never do it. Maybe if I had dozens of executable files that all required the same DLL and I didn’t have an installer, and I wanted to conserve size, which probably wouldn’t happen for me since I am pretty good at creating a quick installer. Though you might be in this a situation.
The third option would make sense if I was planning on running my executable after an install. During the install I could include the VC++ Runtime Redistributable and all would be fine.
Statically Linking the DLLs
Make sure you resolve it for both Release and Debug. The steps are slightly different.
Release
- In Visual Studio, I went to the project Properties.
- I changed my Configuration to Release.
- I went under Configuration Properties | C/C++ | Code Generation
- Look at the Runtime Library setting. It is set to this: Multi-threaded DLL (/MD)
Change it to this: Multi-threaded (/MT) - Rebuild.
Debug
Almost exactly the same as release.
- In Visual Studio, I went to the project Properties.
- I changed my Configuration to Debug.
- I went under Configuration Properties | C/C++ | Code Generation
- Look at the Runtime Library setting. It is set to this: Multi-threaded Debug DLL (/MDd)
Change it to this: Multi-threaded Debug (/MTd) - Rebuild the debug
It might be a good idea for me to figure out how to change the project so when I create a new project of this type, those settings are the default.
if you give a download link for this dll , would be great , i cant found it.
You don't download the dll alone, you download the Microsoft Visual C++ Redistributable installer.

you rock! the 3rd option worked
Thanks a zillion
הודעה זו מופיעה פעמים רבות וברצוני לבטלה!!!
I had the same error message and just un-installed Google Chrome, then re-installed it. It is now working just fine.
Great!
I got stuck with this problem and your post gave me the solution.
Thankls a lot for sharing your knowledge.
Regards.
I get this error.... but don't have Visual Studio.... The only thing I can think of is that a co-worker sent me a presentation video recently and I've been receiving this message ever since.... Thoughts on how to fix it?
Try solution 3, install the Microsoft Visual C++ 2010 Redistributable Package. It is downloadable from Microsoft's web site.
thanks for the support its working fine ..
Thank you - that was a nice quick fix!
[...] I am not going to explain the solution again here, because it is all documented here: Avoiding the MSVCR100.dll or MSVCR100D.dll is missing error [...]
Thanx... I have tested ur 2nd option too it also works fine .cheers
Oh my gosh, I wish I found you 3 weeks ago.... What a small and stupid setting change that worked! You are the man, thank you so much. Also, I really appreciate the walk through too often people assume that you will know exactly what buttons to click. I wish everyone on the internet could answer questions this easily. As a side note, I will never understand why Microsoft assumes that just because I know how to write a program that I will know every single compiler setting to get the program ready for release.
Save my ass big time. Thank you from Washington DC.
Little question, I do got the files etc, but I get: Can't find accespoint off the procedure ??1critcal_section@Concurreny@@QAE@XZ in the DDl-file MSVCR100.dll
Rebuilding with static libraries in some cases causes:
LIBCMT.lib(crt0.obj) : error LNK2019: unresolved external symbol _main
Others suggest this is due to functions that rely on CRT initialization (e.g. strcmp), no clear answer found. (Nothing to do with ATL in my case.)
Any suggestions?
Not sure, I haven't seen that issue.
Ah cheers man, very clean and easy to follow walk through.
Much thanks
Thanks a lot. This one was very very helpful...

Whoa! This article saved me loads of irritations (and boy, did I already swallow loads of 'em!).
You saved ny butt! Loads of thanks 'cos you're a boy, if you were a girl ....
Glad to be of help!
Hi, I think you forgot about the issue Scharl mentiones. The problem is that if you are using extra static libraries, they have to be compiled with the same 'Runtime Library setting' as your program, where you want to use them.
Otherwise an error like Scharl's will appear. You should update this information in your post. Well written otherwise, maybe a download link for the right .dll would be helpful for some.
You can look here: http://stackoverflow.com/questions/3162325/after-building-exe-using-vs-2010-c-missing-msvcp100-dll
to see how the issue can be solved.
THANKS A LOT! U SAVED ME!
'/clr' and '/MTd' command-line options are incompatible
i get that error every time i try to debug.
I also get this problem, I have been trying to statically link msvcr100d into my program but I get the message "Command line error D8016: '/clr' and '/MTd' command-line options are incompatible" and can't use No common language runtime support.
You're a life saver. Thank you!
Thanks for this man it helped me a lot
Thanks so much. I appreciate not only the steps to fix the problem, but also the explanation of what the file is and other potential solutions! Well written.
O-M-G.
Thanks so much!
thanks - exactly this fixed my problem
thank you very much
Thank You, this is exactly what I needed to fix my problem!
Make sure if your running VS2010 (with SP1) installed - that you have the right redist

At present - its in beta...
Ahm... What`s the effect if my msvcr100.dll is remove from my system32???
Will my computer be broken or something???
Will my computer be slow???
what if I edited it for example I replace my original msvcr100.dll that has a size of 752b to 732b or vice versa...
ASAP!!!...
Thanks for the tip! Your instructions are extremely well-written.
It's a joy to read instructions that actually include all of the steps, unlike most of the Java how-to's I've found.
Well, this would be neat if it worked but I get errors such as:

when compiling with /MT.
Any idea?
Everything says it is already defined. You must have an unrelated issue.
no i get this exact same error when setting debug instead of debug dll. this IS related. i have no idea what the problem is.
You can ignore one of the libs in the library config options or set the option to allow for multiple defined symbols
thanks for helping me out i really needed this i was looking all over the internet and u are the only one who helped me
Greetings, Darren
Yeah...same thing when I was first looking for this. The information was there, but wasn't clear or well-written. Hopefully my post is both clear and well-written.
Thanks, well written and it solved same issue I was having.
thank you for saving my time mate!
Glad to help.
Thanks a ton!
