Hi, Please try the below steps to resolve this issue:  1. Open Regedit and navigate to HKEY_CURRENT_USER\Software\InstallShield\22.0  version.  2. Change the value of all the registry keys available to 0 then close Regedit.  3. Open InstallShield 2015 and attempt offline activation.  Make sure that you return the license first from the original machine then only try activation in your same machine. Please let me know if these steps worked for you or not. ... View more
