I have the same problem. The freezing is relative to the "Installing License Manager".
I have tried to not installing the license manager and it works (just unticking install license manager).
The I try to install the license maanger but it is freezing at 75%.
I do not know what to do. CentOS 6.9 64 bit on virtual machine.
I have a proxy but this is configured in the CentOS.
i can surf on Internet and yum can get the librarires.
Any suggestion apart to work with 32 bit?
