In my C++ project I use various open source libraries. I recently migrated from Visual Studio 2013 to Visual Studio 2017. When I migrated, the latest version of the visual studio 2017 was version 15.4.2. Hence I recompiled all the open source libraries with this version of the visual studio. Now, I see that newer version of the Visual Studio is available. If I migrate to the newer version of the Visual Studio 2017, do I have to rebuild these open source libraries again? Or can they still work seamlessly? Would there be any runtime issues?
No, it should still works fine.

I have a solution that was compiled with MSVC 12.0 Visual Studio 2013 (C++/CLI and C#) but only have Visual Studio 2015 (Community). I want to build the project using MSVC 12.0 as it was intended, as I only need to rebuild 1 part of the solution (of 5) for my purpose and want it to be compatible with the other DLLs. When trying to build it from MSVC 14.0 (Visual Studio 2015) it says:
C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.Cpp.Platform.targets(57,5): error MSB8020: The build tools for v120 (Platform Toolset = 'v120') cannot be found.
Of course I installed the MS Build tools for 2013 (MSVC 12.0, v120) from here: https://www.microsoft.com/en-us/download/details.aspx?id=40760 as well as the Microsoft Visual C++ Redistributable 2013 package.
And the right directory for the 12.0 build tools install is C:\Program Files (x86)\MSBuild\12.0\Bin\amd64
It looks like a configuration error on the solution (or in Visual Studio in general) since it is looking for the build tools in the wrong directory. Does anyone know what settings I need to change / add in Visual Studio to get it to compile with MSBuild 12.0 instead of 14.0? I'd prefer not to install Visual Studio 2013 since I don't use it for anything else (just want to have the option to use VS 2013 MSBUILD within VS 2015 as needed).
Okay I have gotten this working although in a roundabout way. Thanks others that have answered and commented. Sign up for a Microsoft Visual Studio Dev Essentials subscription for free. https://azure.microsoft.com/en-us/pricing/member-offers/vs-dev-essentials/ Then you can go through the menus and download Visual Studio Community 2013 by going to this link and finding it https://my.visualstudio.com/downloads. After doing so, you can build MSVC 12.0 from Visual Studio 2015. Sure, not perfect, but it works. I haven't tried uninstalling Visual Studio 2013 to see if it still works (Windows Phone SDK 8.1 is installed with 2013 as was mentioned to get it working in the Enterprise version of 2015) but if you could somehow keep that and remove the 2013 edition I believe it could work without 2013 installed...
If you go to the top of your .vcxproj change it to this
<Project DefaultTargets="Build" ToolsVersion="12.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
Then your .sln can still open in Visual Studio 2015
VisualStudioVersion = 14.0.25420.1
The reason is because the compiler version is specified on a project-by-project basis, and will override the solution version.
I'd prefer not to install Visual Studio 2013 since I don't use it for anything else (just want to have the option to use VS 2013 MSBUILD within VS 2015 as needed).
You can install VS2013 toolset version from your VS2015 installer without installing visual studio 2013. From the 2015 installer, select Windows 8.1 and Windows Phone 8.0/8.1 Tools and common Tools for Visual C++ 2015:
After installation completed, you will find the platform Toolset below:
Then you can built your project with platform toolset Visual Studio 2013(v120).
You can refer to more info from the similar question on SO.
How can I install visual studio 2013 with c++ 2010, 2012 and 2013 toolsets without installing any other visual studio versions (express or any other versions).
I need this so that I can keep my pc light and clean. Are there any alternatives to installing multiple visual studio versions for c++ toolsets?
I am developing a plugin for a program that has multiple version each compiled in c++ 2010 and c++ 2012 so I need those version of c++ toolset. For daily use I need visual studio 2013.
In the end I installed the express editions that use around 800mb each and do not add so much clutter.
MSDN's website says that if you want the C++ 2010 and C++ 2012 toolsets with VS2013, you'll need to install those VS versions on that particular machine. Link here
I don't think there are other alternatives to that.
I just bought a new computer, with Windows 8.1 64bit installed and wanted to start developing in C++.I am new to Visual Studio, I used to do it with eclipse but suggestions I found in the internet were to prefer Visual Studio.
I tried to download Visual Studio C++ 2008 redistributable package (x64) from here http://www.microsoft.com/en-us/download/details.aspx?id=15336.
But I couldn't find where it was stored in my computer, after searching it with key words. Then I uninstalled it, to install again from scratch.
To uninstall it I opened my control panel and it saw that I have Microsoft Visual C++ 2012 Redistributable (x86) installed already, assuming it comes with the computer I bought, and the date of installation matches this. I can't find though where it is stored so I can't open it.
When downloading Visual Studio 2008, it says I need to uninstall previous Visual Studio versions.
Bottom line:
Should I uninstall the Visual 2012 (x86) that probably came with the computer (which is 64bit)? Or should I use it (and try to find where is it located)?
If I shouldn't use the 2012: Was the 2008 version I tried to install good? (2008 gives an "old" intuition, but just my intuition).
Is there an easy way to find out where the application is located for excecution? Any specific file to look for?
thank you
You want to download thee actual Visual Studio IDE from http://www.visualstudio.com/ . Try downloading the free Community Edition for a start.
The Visual Studio redistributable packages are actually the minimal runtime libraries to run C++ programs that were compiled with visual studio. You got a version installed by default even on fresh computers, otherwise you can't run many programs (they are also included with the IDE).
The redistributables are also often bundled with installers to make sure that others can run your programs.
The VC++ Redistributable packages only include the libraries required to run applications built with the respective version of Visual Studio (for example Microsoft Visual C++ 2012 Redistributable is for Visual Studio 2012).
It does not include any version of Visual Studio.
You could uninstall Microsoft Visual C++ 2012 Redistributable (x86) but however as it was preinstalled on your computer, I imagine that some program pre-installed by the computer manufacturer requires it. It's probably not a good idea to remove that.
So no, it's not a good idea to remove it.
In order to use the 2012 version of Microsoft Visual C++ 2012 Redistributable you should install the vs120 compiler, aka the VC++ compiler that comes with Microsoft Visual Studio 2012.
For developing with Microsoft Visual Studio 2008, using Microsoft Visual C++ 2008 Redistributable is completely fine as it matches the compiler version. However if you want to use the newer 2010, 2012, 2013, and 2015 versions you need to use those respective versions of the Microsoft Visual C++ Redistributable.
If you wish to use an up-to-date version of Visual Studio, try the Visual Studio 2013 Community Edition, or if you're feeling adventurous try the Visual Studio 2015 Release Candidate.
The application you built is always located in the project's directory, under /Debug or /Release, depending on whether you built a debug or release version of the application. If you do not know where your project folder is located you may right-click your project in the File pane and click Open folder in Windows Explorer.
All my C++ Visual Studio 2012 projects cannot be upgraded by VS 2013 Professional Update 2, microsoft tells that you also need to have VS2012 installed in order to open VS 2012 projects.
The problem is that I have installed VS2012 and still get the same error.
after each project name in VS 2013 I have (Project incompatible), I want to convert the projects to VS2013 because I don't want to use VS2012 anymore.
Unsupported
This version of Visual Studio is unable to open the following projects. The project types may not be installed or this version of Visual Studio may not support them.
For more information on enabling these project types or otherwise migrating your assets, please see the details in the "Migration Report" displayed after clicking OK.
No changes required
These projects can be opened in Visual Studio 2013, Visual Studio 2012, and Visual Studio 2010 SP1 without changing them.
and this is the error in migration report
The application which this project type is based on was not found.
I found somewhere on a forum that if you install VS 2012 SDK it should work, but the VS2012 SDK cannot be installed because it cannot find Visual Studio 2012
Every time I want to compile my Visual Studio project I get the message that MSVCP120d.dll is missing. Google can't help me. I already installed some redistributables but they didn't help. I also found this:
Msvcp120d.dll Debug version of C++ runtime. No redistribution
allowed.

From the comments, the problem was caused by using dlls that were built with Visual Studio 2013 in a project compiled with Visual Studio 2012. The reason for this was a third party library named the folders containing the dlls vc11, vc12. One has to be careful with any system that uses the compiler version (less than 4 digits) since this does not match the version of Visual Studio (except for Visual Studio 2010).
vc8 = Visual Studio 2005
vc9 = Visual Studio 2008
vc10 = Visual Studio 2010
vc11 = Visual Studio 2012
vc12 = Visual Studio 2013
vc14 = Visual Studio 2015
vc15 = Visual Studio 2017
vc16 = Visual Studio 2019
The Microsoft C++ runtime dlls use a 2 or 3 digit code also based on the compiler version not the version of Visual Studio.
MSVCP80.DLL is from Visual Studio 2005
MSVCP90.DLL is from Visual Studio 2008
MSVCP100.DLL is from Visual Studio 2010
MSVCP110.DLL is from Visual Studio 2012
MSVCP120.DLL is from Visual Studio 2013
MSVCP140.DLL is from Visual Studio 2015, 2017 and 2019
There is binary compatibility between Visual Studio 2015, 2017 and 2019.
I have found myself wasting time searching for a solution on this, and i suspect doing it again in future. So here's a note to myself and others who might find this useful.
If MSVCP120.DLL is missing, that means you have not installed Visual C++ Redistributable Packages for Visual Studio 2013 (x86 and x64). Install that, restart and you should find this file in c:\Windows\System32 .
Now if MSVCP120D.DLL is missing, this means that the application you are trying to run is built in Debug mode. As OP has mentioned, the debug version of the runtime is NOT distributable.
So what do we do?
Well, there is one option that I know of: Go to your Project's Debug configuration > C/C++ > Code Generation > Runtime Library and select Multi-threaded Debug (/MTd). This will statically link MSVCP120D.dll into your executable.
There is also a quick-fix if you just want to get something up quickly: Copy the MSVCP120D.DLL from sys32 (mine is C:\Windows\System32) folder. You may also need MSVCR120D.DLL.
Addendum to the quick fix: To reduce guesswork, you can use dependency walker. Open your application with dependency walker, and you'll see what dll files are needed.
For example, my recent application was built in Visual Studio 2015 (Windows 10 64-bit machine) and I am targeting it to a 32-bit Windows XP machine. Using dependency walker, my application (see screenshot) needs the following files:
opencv_*.dll <-- my own dll files (might also have dependency)
msvcp140d.dll <-- SysWOW64\msvcp140d.dll
kernel32.dll <-- SysWOW64\kernel32.dll
vcruntime140d.dll <-- SysWOW64\vcruntime140d.dll
ucrtbased.dll <-- SysWOW64\ucrtbased.dll
Aside from the opencv* files that I have built, I would also need to copy the system files from C:\Windows\SysWow64 (System32 for 32-bit).
You're welcome. :-)
I have the same problem with you when I implement OpenCV 2.4.11 on VS 2015.
I tried to solve this problem by three methods one by one but they didn't work:
download MSVCP120.DLL online and add it to windows path and OpenCV bin file path
install Visual C++ Redistributable Packages for Visual Studio 2013 both x86 and x86
adjust Debug mode. Go to configuration > C/C++ > Code Generation > Runtime Library and select Multi-threaded Debug (/MTd)
Finally I solved this problem by reinstalling VS2015 with selecting all the options that can be installed, it takes a lot space but it really works.
I downloaded msvcr120d.dll and msvcp120d.dll for 32-bit version and then, I put them into Debug folder of my project. It worked well. (My computer is 64-bit version)
My problem was with x64 compilations deployed to a remote testing machine. I found the x64 versions of msvp120d.dll and msvcr120d.dll in
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\redist\Debug_NonRedist\x64\Microsoft.VC120.DebugCRT
I had the same problem in Visual Studio Pro 2017: missing MSVCP120.dll file in Release mode and missing MSVCP120d.dll file in Debug mode.
I installed Visual C++ Redistributable Packages for Visual Studio 2013 and Update for Visual C++ 2013 and Visual C++ Redistributable Package as suggested here Microsoft answer this fixed the release mode.
For the debug mode what eventually worked was to copy msvcp120d.dll and msvcr120d.dll from a different computer (with Visual studio 2013) into C:\Windows\System32
Alternate approach : without installation of Redistributable package.
Check out in some github for the relevant dll, some people upload the reference dll for their application dependency.
you can download and use them in your project , I have used and run them successfully.
example : https://github.com/Emotiv/community-sdk/find/master
I was building my application on VS 2019 when this issue came up. You can copy these DLLs from this location into debug directory of your application to get going.
