If you are using Modbus Poll for work, ask your employer to buy a license. The corporate license costs around $98 USD. Compared to an hour of your troubleshooting time, that is nothing. One hour of factory downtime costs thousands.

If you are a student or hobbyist, use QModMaster or pay the discounted hobbyist fee. Your computer's security and your professional reputation are worth far more than the €15 you would save by hunting for a malware-laced "registration key."

Stay safe, and keep your serial lines clean.

Have you found a "cracked" version of Modbus Poll 2021? Assume it is a Remote Access Trojan. Scan it on VirusTotal before execution—but the safest action is to delete it immediately.
