RouterCAM 3 vs 4: activation codes are major-version specific Source-Date (SAST): 2025-03-18 11:20; 3.11.20 ceiling 2025-03-10 20:01 Dest: both Review-after: 2027-08-31 Status: current Facts RouterCAM 3 and RouterCAM 4 are two different software. An activation code works only for that major version. The paper that ships with the code states whether it is for RouterCAM 3 or RouterCAM 4. A RouterCAM 3 code will not activate RouterCAM 4 (and the reverse). RouterCAM 3 upgrades only as far as 3.11.20; it does not upgrade to RouterCAM 4. Later EnRoute-as-replacement notes are on the SAi EnRoute vs RouterCAM page.
