I have old information sitting on QV version 6. I have a new PC where I have only the version 11 installed. I have followed QlikTech recommendation and moved it to a secure place on my hard drive and uninstalled it. Now I am trying to install the old version 6.05 and it works well, but I cannot contact the License Enabling server (I have tried with an unsecured access, i.e. no proxy/firewall).
I have my license number and control number. I have tried to generate a LEF.txt file but it is unrecognized by the version.
