Make sure your system meets the System Requirements.

Microsoft Visual Studio* is required for installations on Windows. The installer checks for it. If you do not have Microsoft Visual Studio, you can install one of the following versions:

• Visual Studio 2019 
• Visual Studio 2022 
• Visual Studio build tools 2019 
• Visual Studio build tools 2022 

For more information, see Visual Studio 2019 or Visual Studio 2022 
Before enabling integration through the oneAPI toolkit installer, install the desktop development with C++ workload into each Visual Studio instance.

Make sure your system meets the System Requirements.

The Intel Fortran Compiler has hardware and software prerequisites. For a complete list, see Intel® Fortran Compiler System Requirements.

Before running the containers, install Docker as described in the Docker Installation Instructions.

1. To launch the GUI installer, select the .exe file.
2. Follow the instructions in the installer. ​​​​​​

1. To launch the GUI installer, select the .exe file.
2. Follow the instructions in the installer.

​1. Review the options in Command Line Installation Parameters.

2. Download the toolkit:

wget https://registrationcenter-download.intel.com/akdlm/IRC_NAS/2bff9d18-ac2b-40b1-8167-00156f466b0e/intel-fortran-essentials-2025.0.0.301_offline.exe

3. Update the following with your selected parameters:

• For a silent installation, enter the following command:

sudo sh ./intel-fortran-essentials-2025.0.0.301_offline.exe -a --silent --eula accept

In silent mode, integration into Microsoft Visual Studio is by default (if supported). You need to install the desktop development with a C++ workload into each Visual Studio instance.

• To skip Visual Studio integration, pass the following arguments to the installation command: -p=NEED_VSXXXX_INTEGRATION=0, where XXXX is the Visual Studio version. For example, to install a toolkit and skip integration into Visual Studio 2019, use the following installation command:

intel-fortran-essentials-2025.0.0.301_offline.exe -s -a --silent --eula accept -p=NEED_VS2019_INTEGRATION=0

4. After the installation is complete, verify that the toolkit is installed in the default directory: C:\Program Files(x86)\Intel\oneAPI.

1. To launch the GUI installer, select the .exe file.

There are two methods to verify that the tools are installed correctly. Pick the one that works for you. Matrix Multiply is a simple sample used in both methods.

• Command-line browser (recommended)
• Microsoft Visual Studio Code

Command-line browser (recommended)

To use the oneAPI sample browser utility:

1. Create a folder where you want to store your sample. For example, C:\samples\matrix-mul

2. Open a command window. 

3. Set system variables by running setvars. There are two variants; for component directory and unified directory layouts.

• Component Directory Layout: "C:\Program Files (x86)\Intel\oneAPI\setvars.bat"

Note: For Windows* PowerShell* users, enter this command:

cmd.exe "/K" '"C:\Program Files (x86)\Intel\oneAPI\setvars.bat" && powershell'

• Unified Directory Layout: "C:\Program Files (x86)\Intel\oneAPI\<toolkit-version>\oneapi-vars.bat"

Note: For Windows PowerShell* users, enter this command:

cmd.exe "/K" '"C:\Program Files (x86)\Intel\oneAPI\<toolkit-version>\oneapi-vars.bat" && powershell'

The previous command assumes you installed to the default folder. If you customized the installation folder, setvars | oneapi-vars is in your custom folder.

4. To launch the oneAPI Samples browser utility, run the following command: oneapi-cli.

5. Press the up and down arrow keys to navigate to the sample: Create a project > cpp > Matrix Multiply.

6. To to select the sample, press Enter. 

7. Specify the project's location. The default location includes the path from where the utility was run and the name of the project. 

8. Press Tab to select Create and then press Enter. 

9. Configure the build system and build the Matrix Multiply sample as described in the sample documentation.
