Can you clarify: Did you just copy a.lic file from the activations folder on your old laptop to your new one, and copied the wrong one? Or did you enter the wrong 10 digit serial number during the installation process? Usually you use the MAC ID of your main Ethernet card, or the Volume ID of your C: drive, or a special USB dongle from RA.Creating a new License file for a new computer is called 're-hosting' and you can do it online or by calling Rockwell Automation Technical Support. The activation file was not tied to a particular value you enter during installation or to a particular computer.The OP probably has a FactoryTalk activation, which is tied to a particular hardware identifier on the computer.Raoul's suggestion is right: you need to generate a new.LIC file that uses a hardware ID on the new computer. The 'installation diskette' hackcoder refers to was the old EVRSI activation system.

Logix only cares about the first 4 numbers of the serial number.Standard starts with 1203Pro starts with 2022Mini starts with 1635Full starts with 2445Edit: I forgot to list the paths for the XP registry keys:HKEYLOCALMACHINESOFTWARERockwell SoftwareRSLogix 5000.1Last VersionUserInfoSerialnumHKEYLOCALMACHINESOFTWARERockwell SoftwareRSLogix 5000.1SupportProductIDHKEYLOCALMACHINESOFTWARERockwell SoftwareRSLogix 5000.1UserInfoSerialnum. The fix for this is to modify the registry!On 64-Bit systems, these are the keys that need to be modified:HKEYLOCALMACHINESOFTWAREWOW6432NodeRockwell SoftwareRSLogix 5000.1Last VersionUserInfoSerialnumHKEYLOCALMACHINESOFTWAREWOW6432NodeRockwell SoftwareRSLogix 5000.1SupportProductIDHKEYLOCALMACHINESOFTWAREWOW6432NodeRockwell SoftwareRSLogix 5000.1UserInfoSerialnumChange the serial numbers listed in all 3 of these keys to the correct serial number and then your activation will work.
