Installing Symantec Endpoint 11.0.5 client onto a Windows 7 64-bit client (the as yet undocumented method)
I was unable to install the Symantec Endpoint 64-bit client via push from the server console (Windows 2003 32-bit Std.) to my 64-bit Windows 7 machine. Instead, I had to explode the Symantec_Endpoint_Protection_11.0.5_AllWin_EN_CD1 zip file and, from there, right click on the setup.exe file and change the compatibility to Vista 32-bit. The client program finally installed into the Program Files (x86) folder.
I then followed the instructions in Document ID:
2008110714513748 "How to change a Symantec Endpoint Protection client from unmanaged to managed in MR3 and later". This worked and my Windows 7 64-bit computer now appears as a managed computer in the Symantec Endpoint Console on the server. And, the amazing thing is that my system is recognized as running "Windows 7 Professional Edition" in the Operating System column! There certainly is some kind of disconnect in the push installation package from the server on this score.
