As stated in the license agreement, "Flexera Software grants Licensee the right to install and use the software on a single computer to be used exclusively with Visual Studio and the right to install and use up to two (2) additional instances for use within a Team Foundation Server environment".
The latter is exactly what I did: i installed the InstallShield 2012 Limited Edition on a Team Build machine (Team Foundation System 2012), where no installations of Visual Studio exist. Now, I can correctly compile and build my solution containing an ISL project. The problem is that when I run the built setup.exe, a message stating "This Setup was created with an EVALUATION VERSION of InstallShield" is shown.
So, the question is: how can I activate InstallShield 2012 Limited Edition on a Team Build machine where Visual Studio hasn't been installed?
