(Note: As of 2024-2025, legacy software may require creating a free account and proving instrument ownership via serial number.)

Here is the most critical section. Sokkia ProLink 1.15 is proprietary software owned by Sokkia (now part of Topcon Positioning Group). However, Sokkia historically provided this version at no cost to registered instrument owners. You can legally obtain it for free through: sokkia prolink 1.15 software free download

Warning: Avoid third-party "cracked" or "keygen" sites. These often contain malware, ransomware, or altered executables that can damage your field computer or infect your total station’s file system. Always verify the hash (MD5/SHA) of the installer if possible. Warning: Avoid third-party "cracked" or "keygen" sites

Despite newer versions (e.g., ProLink 2.0 or 3.0), version 1.15 retains a loyal following for three reasons: ProLink 2.0 or 3.0)

This is a grey area. Officially, Sokkia (now owned by Topcon Positioning Group) does not actively distribute ProLink 1.15 as a public free download on their main website. The software is considered "End of Life" (EOL).

However, because it was never tightly locked with activation keys or hardware dongles, many third-party repositories, surveying forums, and legacy driver sites host the installer. Legally, if you own a Sokkia instrument that originally came with ProLink, you are entitled to use it. Downloading it from a third party is technically piracy if you never owned a license, but in practice, Sokkia has rarely enforced this for EOL freeware.
