can we transfer the license of Staad.pro to another PC permanently?
Yes, you can lock or "check out" licenses for STAAD.Pro and any necessary design codes to a computer for dedicated use. The following support solution provides instructions for checking out a license. This procedure provides the ability to secure a license for a machine, typically for a year at a time, so that it can be used regardless of an Internet connection.
Important: A checked out license will log one usage continuously until it expires or is checked in early. Note that unless you have more than one license of STAAD.Pro, use of the product on another machine will result in overuse unless the license on the first machine is checked in or expires.
