License Manager

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.

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.

Borrowing & returning licenses

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.

License management command line options

IDA recognizes the -Olicense command-line switch, with the following format:

  1. -Olicense:keyfile=<path-to-.hexlic-file>[:setpref]

  2. -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:

  1. the preferred license information possibly stored in the registry, and

  2. the IDA_LICENSE environment variable

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.

License management environment variable

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>:…
