I don't believe it is supported at this time - http://kc.mcafee.com/corporate/index?page=content&id=KB68147
I downloaded it and now everytime I check it says in red that is not monitoring in live mode. It still scans and updates ,but I can't use virtual " tech" or contact McAfee.

The answer is:
1. Download the McAfeeDLPEndpoint93Patch1Licensed.zip by your Grant Number.
2. Open and extract the HDLP_Agent_9_3_100_52.zip.
3. Now youcan find the DLPAgentInstaller.x64.exe or DLPAgentInstaller.x86.exe which is 100% working with WIN 7 x64 compatibility.
Your steps may be fine for W7 64bit, but here we are discussing Windows 8.1 - which is NOT supported at the moment.
