Do not look for "KTS 570.exe." Instead, search on the official Bosch website for "ESI[tronic] Download Manager."

Email support@boschdiagnostics.com with your KTS 570 serial number. Request the "Offline Installation Package (ISO)." They often provide a private FTP link.

Once installed, the Bosic ESI[tronic] Update Manager will open. This tool manages your KTS 570 software download.

Windows 8, 10, and 11 frequently block unsigned drivers. The KTS 570 drivers are often older, requiring a special installation process.
