Kuka Sim - Pro 31 Product Key Upd

The steps to update a product key can vary. Here’s a general approach:

| Symptom | Likely Cause | Fix | |---------|--------------|-----| | “Unable to connect to license server” | Network firewall, proxy, or offline machine. | Ensure outbound HTTPS to license.kuka.com is allowed; disable VPN temporarily. | | “Invalid product key” | Typo, extra spaces, or using a key meant for a different version (e.g., SIM PRO 30). | Double‑check the key string; copy‑paste directly from the email. | | “License bound to another hardware” | The key is already tied to a different computer. | Contact KUKA support for a re‑binding request (they usually require proof of purchase). | | “License expired” | The key’s validity period has ended. | Purchase a renewal or extension; then repeat the activation steps. | | SIM PRO crashes on startup | Corrupted license cache. | Delete the license.dat file (usually located in %APPDATA%\KUKA\SIMPRO\) and re‑register the key. | kuka sim pro 31 product key upd
