To download a pre-installed version of JASP for Windows, click on one of the two buttons below. If you’re not sure whether to download the 32-bit or the 64-bit version, check this guide from Windows.
On Windows, JASP needs the Microsoft Visual C++ Redistributable for Visual Studio 2017. This is automatically installed with the JASP setup. A ZIP file will not install this package, you need to do that manually. To do this, download the 32 bit version or the 64 bit version of the setup and run it.
