Download Documentation: Intel® Compiler (Current and Previous)

Download Instructions

Use the following steps to add Intel® Compiler documentation to your local machine:

1. Download your selected HTML documentation from the links in the Download Links section.
2. Unzip the downloaded documentation folder to one of the following locations:
   • Paths for oneAPI:
     • Intel® oneAPI DPC++/C++ Compiler or Intel® C++ Compiler Classic: C:\Program Files (x86)\Intel\oneAPI\compiler\[version]\windows\documentation\en\compiler_c\
     • Intel® Fortran Compiler: C:\Program Files (x86)\Intel\oneAPI\compiler\[version]\windows\documentation\en\compiler_f\
   • Paths for PSXE and ISS:
     • Intel® C++ Compiler: C:\Program Files (x86)\IntelSWTools\documentation_YYYY\en\compiler_c\
     • Intel® Fortran Compiler: C:\Program Files (x86)\IntelSWTools\documentation_YYYY\en\compiler_f\

3. Restart Microsoft Visual Studio*.
4. Use F1 help as expected.

F1 help works for Intel specific keywords, all other keywords redirect to a Microsoft* landing page. For the best search experience, use a Google Chrome* or Internet Explorer* browser to view your downloaded copy of the Developer Guide and Reference. If you use Mozilla Firefox*, you may encounter an issue where the Search tab does not work. As a workaround, you can use the Contents and Index tabs or a third-party search tool to find your content.

NOTE: The Intel® oneAPI DPC++/C++ Compiler Developer Guide and Reference and Intel C++ Compiler Classic Developer Guide and Reference documents will overwrite each other. Keep this in mind when you are using the path in step 2. 

Intel® C++ Compiler Classic (icc) is deprecated and will be removed in a oneAPI release in the second half of 2023. Intel recommends that customers transition now to using the LLVM-based Intel® oneAPI DPC++/C++ Compiler (icx) for continued Windows* and Linux* support, new language support, new language features, and optimizations.
