I've been trying to run a C# project in Visual Studio and keep getting hit with the error:
'"dotnet.exe"' is not recognized as an internal or external command,
operable program or batch file.
From what I've seen online, several people have managed to fix this by messing around with the SDK or with the 'path' environment variables in Window's System properties tab. The problem is, I have no idea what any of these system settings and specifications do, and I can't get a clear answer.
I can tell that VS isn't able to get dotnet working, so what ideas come to mind to fix this error?
Install the DotNet Core Runtime or SDK (I use latest version)
The SDK has all the tools needed for development (including the runtime), while the Runtime is needed for running dotnet core applications.
After installation, you will need to restart the PC yourself so that the data entered in the PATH variable are available
Runtime link
Check if you have %ProgramFiles%\dotnet\ folder in your PC, that's where the dotnet.exe file should be.
If you found none, that mean you have not installed .NET Core SDK/Runtime. As you have VS, I am assuming you are writing some code with it, you should install the SDK from here.
If you have the folder but still have the problem, go to your Environment Variable, add that folder to the end of PATH variable and restart the PC.

I am getting an issue with installing the .NET SDK, at first when I went into visual studio 2019 it said that I was missing the dotnet runtime sdk so I installed it like it asked and restarted my computer. I then went on to visual studio 2019 again, and the same issue arose, I went into my command prompt and typed dotnet --list-sdks and it displayed no sdks. I have all of the runtimes installed, but it says No SDKs were found. image . I tried re-installing the sdks but the same problem stuck. I even went as far as to re-install IIS. I can't do anything without this being fixed please help soon!
Before you try a manual install, I'd check if the Path in the system's environment variables is correctly configured for your system.
Given that there's always one shared host that moves forward, it will either pick the x86 or the x64 version on your machine. This issue of not picking the right one might happen if you install multiple/different versions.
Run the where.exe dotnet command to see where the host is looking for the SDK (it's the first entry returned). If you're on a x64 machine, you want to have C:\Program Files\dotnet listed first.
If it's not, edit the Path system's environment variable to have the location you want showing up higher. Doing that should fix the issue of the SDK versions you installed not showing up when you run dotnet --info.
See The latest installed .NET SDK not found for complete instructions.
Answer above by Maira is correct and fixed the issue however for those that need a little help go to start menu, type "path" and select "Edit the System Environment variables". When that opens, under the "Advanced" tab click "Environment Variables".
Under System Variables find the "Path" variable and click "Edit". Find "C:\Program Files\dotnet" and click "Move Up" so that it is above the (x86) variable.
I managed to find the answer to this problem, and anyone else who is having this problem can most likely fix it with this solution too! So the reason it breaks is because of the way the .NET Core SDK installer works, it does not install the SDK correctly for some reason, so you have to do it manually. Go to this link, where you would normally get the installer for the SDK but rather than downloading the normal version, download the binaries version. It should download as a .zip, so extract it and then copy the contents of the folder. Go to C:\Program Files (x86)\dotnet\ and then remove it's contents, finally paste your clipboard into the folder. Now try it out, open a new command prompt or PowerShell, and type dotnet --info. It should tell you that you have all the SDK's and Runtimes installed. Keep in mind, you will have to download the newest version of the binaries, that way you have the latest version of the SDK's.
The reason this works is that you are manually pasting the SDK's into the folder, if anyone could start a ticket for the installer to Microsoft, {EDIT: MS created an internal ticket and this answer is wrong. See next answer End Edit} that would be great, and link them to this post so that they can understand what's going on. Some of you might have come here because you are fed up with reading Microsoft documentation and to be honest, so was I! Now this might not fix all the problems you are having, for example, I am still having problems with visual studio and their .NET implementation but if I or anyone figures it out, I will add it to this answer. Hope you have a great day, bye!
dotnet do not seem to match well with SDKs / runtimes with 32-bits and 64-bits. If you have both variants and want to only use the 64-bits (or generally, cant list up any SDK-s), you can try this :
Inside folder : C:\Program Files (x86)
Rename folder 'dotnet' to 'dotnet_x68'
Inside a shell (remember to either run command 'refreshenv' from Chocolatey for example to refresh your environment, if you have choco installed.. )
Enter now this command :
dotnet --info
Also list the SDKS :
dotnet --list-sdks
This fixed up my development environment. Note that if you want to use dotnet against x86 system, you might consider to instead uninstall x64 variants of dotnet runtime and sdks as dotnet do not seem to work very good from command line with a mix of them both (and avoid renaming the x86 folder of dotnet of course as suggested above.
I found that I had two program files, One called Program Files (x86) and one called Program Files. I went to Settings, About and looked at my System Type. I have a 64-Bit operating system and so I went into Program Files (x86) and found another dotnet folder. I deleted the dotnet folder and restarted Visual Studio. It Worked after that.
If you get this issue like I did on a ARM based Mac M1 or M2 then do the following.
remove this directory completely /usr/local/share/dotnet
run the installer package again
I believe this issue happened when I accidentally installed dotnet-ef x64 instead of arm64.
I have an MVC5 application which I'm trying to run offline. I installed VS2017 offline but when I try to build the project it throws multiple errors relating to it missing all the .NET assemblies and dlls. When I try to add these assemblies they're not available to be added. Anyone please help.
PS: there's NO internet on the machine.
I also have that problem from time to time. What usually helps is to do a dotnet restore. This is different to running restore from the solution explorer within VS, you have to do it through the command line. In order to execute it, you need to have the .NET Core SDK installed. dotnet restore is usually very good at fixing some project problems such as corrupted .json files that VS creates behind the scenes and I would guess that it is able to repair those files without internet connection, but I haven't tried.
Try cleaning and rebuilding your solution. I had this issue and something went funky with my dll's.
It's obvious omnisharp error same as mine. I changed omnisharp path version from c# extension(c# > unistall > install another version) and reopened to vscode. It worked for my project. All error has gone.
Setup:
Windows 7 64 bit
Visual Studio Code, version 1.30.0
Dotnet version: 2.2.101
I am at the beginning of trying to learn how to program with C# and I have hit a snag.
I am attempting to follow the tutorial https://learn.microsoft.com/en-us/dotnet/core/tutorials/with-visual-studio-code
and I am not getting past the start of it.
The only wrinkle I can think of is that I have installed Visual Studio on my D: drive.
I have checked my environmental variables and I see that if I go into my system variables under the path variables I see C:\program files\dotnet.
Also if I am in the interactive terminal in Visual Studio I can go to the folder location of the dotnet.exe, type in the terminal >dotnet --version
and a dotnet version shows on my terminal.
Do I need to muck with my environment variables or move my dotnet.exe file to the D drive also to get this puppy goin?
you need to download and install .NET Core SDK
https://dotnet.microsoft.com/download
As the other answers mention, I needed to first install .NET.
But after install and restart, the problem persisted for me.
The final fix for me was to click the "Kill Terminal" button and then open a new one.
Apparently the terminal session can survive a restart.
it could be because, maybe you haven't installed the dotnet core yet, which seems to be required prior to installing the asp.net core spa template. To check if you have installed the .net core in your machine or not, check if this exists
C:\Program Files\dotnet\sdk
or just type following in command prompt
dotnet --version
or You need to install .NET SDK separately. You can download and install it from here
I hit install from the installation directory by double-clicking the download and by selecting Repair. (There were two other options Uninstall and Cancel).
After repair, I just typed dotnet --version at the cmd prompt and got the version displayed.
My environment is Windows 10 on AMD64 processor.
I have faced the same issue,
Problem statement:- I have installed dotnet core sdk in my sys, even than when I hit dotnet in command prompt I was getting ,
dotnet-is-not-recognized-as-an-internal-or-external
Solution :- I have added dotnet path to advanced system settings-> Environment variables-> user variables.
Path = "C:\Program Files\dotnet"
refer the image
error solved
I am getting the following error while trying to run Robocode.bat
error: could not find or load main class robocode.robocode
I checked the java Installation, I checked it in the java website, the installation is fine.
I also added the path in environmental variable.
My OS is Windows 8
Also I am trying to install RoboCode for.Net
The problem is, that the bat cannot find the robocode.jar
check if it is still in the lib folder of your installation. and you did not move the bat file
Make sure to follow this instruction (i.e. install the java version of Robocode, then install the Robocode .NET plugin):
.NET plug-in for Robocode must be installed on top of your existing
Robocode directory.

[Old question I know, but I ran into this problem today and didn't see this answer here.]
I downloaded setup.exe, and then begin to install and it immediately crashes.
On win7 it worked fine. On XP it doesn't work.
Error text:
Unable to install or run the
application. The application requires
that assemble stdole Version
7.0.3300.0 be installed in the Global Assembly Cache (GAC) first.
You'll need to include stdole.dll as a required file in your Publish settings in Visual Studio. Once you publish your app again, it should then include that file in your app when it's installed.
More info can be found here.
This happened to a few people that i had to install a click once application i developed. Basically something happened in their installation of .NET and the needed .DLL's were not moved to the GAC. It's very simple to fix, basically You need to copy stdole.dll from C:\Program Files\Microsoft.NET\Primary Interop Assemblies\ to C:\Windows\Assembly ... that should fix your issue. Including them in the application isn't the best idea, this will fix it for ALL click once applications rather then just that one you are currently building.
P.S. Dragging the files to the location will work, you might get an error if you try to copy it.
