Online and Offline Activation Failing
Getting Error 51311 - One or more response actions failed. Not seeing this documented anywhere, and this is happening both online and offline.
Hi @afootit ,
How about trying out below mentioned steps:
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.
