== Upgrading from Noah 3.x to Noah 4.x ==
The Noah 4 upgrade should automatically migrate the license file from a 3.x license to a 4.x license. This can be verified by looking for the license file (noah4.lf) in the following folder:
 * 32 bit machines, ''C:\Program Files\Common Files\HIMSA Shared\Noah4.lf''
 * 64 bit machines, ''C:\Program Files (x86)\Common Files\HIMSA Shared\Noah4.lf''

== Installing Noah 4 on a computer that never previously had Noah ==
Copy the license file (Noah4.lf) from a machine that currently has a Noah 4 license (see path above) or download it {{swdev:howto:noah4license.zip|here}}.
