Before proceeding with the download, users should be aware of a few prerequisites. Multiwfn 3.8 has no heavy dependencies on Windows, but on Linux, a suitable version of gfortran and libc may be required for compiled binaries. Additionally, because the program is distributed as freeware for academic use but not open-source, a registration or simple acknowledgment of the license terms is typically required before download—often just by clicking an “Accept” button. It is also wise to check the file hash (MD5 or SHA256) if provided, to confirm that the download has not been corrupted during transfer.
