Remark 1: The 32 bits Windows binaries will run fine on 64 bits systems, but Orthanc will only have access to less than 4GB of RAM, which might be a limitation for intensive use cases.

Remark 2: Since Orthanc 1.2.0, the installers are provided courtesy of Osimis, the commercial partner of our free and open-source project. After downloading the binaries below, you might be contacted by the Osimis team to assist you in the setup of Orthanc.
