I believe this is known problem with the Tamino 2.3 installation, and this does not occur with 3.1. You can get around the problem by:
1) installing Tamino without it asking for a license file (setup.exe -IGNLIC_FILE) from a command prompt.
2) once the installation is complete you have to add the license file so that you can use Tamino. Use regedit to add a key under: HKLM/Software/Software AG/Tamino/Tamino 2.3.1.4/ with the key called : “license file” with the value: “c:\program files\common files\software ag\LKey\ino231.xml”
and copy the license file from the floppy disk to the above mentioned directory. I’m assuming c: drive is where NT is installed, if this is not the case replace c: with the correct drive letter.
Hope this workaround helps but is only applies to Tamino 2.3.
