I have finally managed to get DRM 188.8.131.52 on my Personal Laptop and it feels amazing.
Hope you have installed and configured the DRM successfully. Could you please share any real time installation guide.
or let me know the steps for configuration. I just installed.
I just followed the oracle installation document for DRM and i got through... Here is the link for it.. this should help...
