I have tested MA 4.0 patch 3 on my windows 7 machine and found the following.
Mcafee endpoint encryption 5.2.0 is installed. When going to the EPO console it is properly detected but when looking on the client under the agents about it reports it as 5.1.7
After running the Agents framepkg_upd.exe updater on my Windows 7 Machine, deployment tasks still do not seem to work. I updated from version 4.0.1444 and I have confirmed that version 4.0.1494 is installed.
