The license manager dialog (Help -> License manager...) lets you pick a license to use IDA with.
Depending on your licensing plan (e.g., floating), you may have the possibility to switch between various licenses located on the same license server (but having different sets of add-ons & decompilers, for example)
The active license is represented in bold in the list. Double-clicking on a line in the list, will make that license active, and make it the preferred license.
Doing so will also make it the "preferred" license -- that is, it will be remembered for later sessions as being the default license to use.
When using floating licenses from a server, it is possible to borrow the license for an extended period of time, thereby allowing offline work. Please use the context menu to achieve that.
IDA recognizes the -Olicense command-line switch, with the following format:
-Olicense:keyfile=<path-to-.hexlic-file>[:setpref]
-Olicense:server[:host=<hostname>][:port=<port>][:lid=<xx-xxxx-xxxx-xx>][:setpref]
Where the optional bits are:
keyfile
Path to the license file
host
The license server host name
port
The license server port
lid
The license ID to use
setpref
Whether the selected license should be remembered as the prefererred license
The command-line switch -Olicense takes precedence over both:
the preferred license information possibly stored in the registry, and
NOTE: The -Olicense switch (or IDA_LICENSE)
will not, by default, overwrite the "preferred" license information in the registry.
Specify setpref to achieve that.
NOTE: On Windows, the <DriveLetter>: scheme is recognized.
Therefore -Olicense:keyfile=C:/tmp/my.hexlic:setpref will work as expected.
Alternatively, the IDA_LICENSE environment variable can be used
to specify licensing information, and accepts the same format
as the -Olicense option
E.g., IDA_LICENSE=server:host=<hostname>:…
