Note: It is the user’s responsibility to ensure certificates are produced with the appropriate version. If a user chooses to inappropriately use an earlier version of FR5 to produce a certificate, they run the risk that a Building Surveyor will reject the certificate leading to further certificate costs.

Note: Installation of minor releases involving a letter change, eg,  v5.2.2b (3.13) to v5.2.2​c (3.13), will by default overwrite the previous version, while major releases involving a number change, eg, v5.2.1 (3.13) to v5.2.2 (3.13), will by default install beside older versions.
