Symantec EndPoint Protection version 11.0 is also capable of playing nice with both Windows 7 client and Windows Server 2008 R2 (Windows 7 Server). According to the company, Symantec Endpoint Protection 11.0.4 can be installed on the Beta development milestones for Windows 7 and Windows Server 2008 R2. At the same time, the security solution will also install and run on builds from the Release Candidate branch of the operating system, but not on the most recent development milestones made available by Microsoft

.

Symantec Endpoint Protection 11.0.4 can be installed on Windows 7 Beta, either 32-bit or 64-bit,” Symantec revealed. “To install MR4 on Windows 7: copy the contents of the Symantec Endpoint Protection folder to your local hard drive or a network share. Run LUSETUP.EXE to install LiveUpdate. Restart the computer. Run SETUP.EXE to install Symantec Endpoint Protection.”

symantec  reponse on the support/compatibility

I'm hearing via my contacts in Symantec that MR4 MP5, expected on 4 Sep 2009, will fully support W7 RTM. The date may change.

Coen66..it is not MR4MP5 it is Just MR5  or 11.0 RU5. Yes it will be released in Sep ,2009 but there is no specfic date for that.

Mip : SEP MR4 and above can be installed on Windows 7, but it is not supoorted.

SEP MR5  will support  Windows 7, Windows 2008 R2, and Windows Vista SP2.

I was extremely disappointed that the Trialware download version is 1.0.4000.2295 - not even the latest publicly-available build.
The clock is ticking, and what I have is completely useless for evaluating on Windows 7 RTM.
If there is a way to upgrade a trialware version prior to expiration, Symantec makes it extremely difficult to find out what it is.
Now that I'm working for myself, I can be only worth a few hundred bucks a year to Synamtec, and they make you feel that way.
Apparently there is no interest in helping you at all unless you are already paying a fat annual maintenance fee; and even then, judging by the resposes I've seen in these forums, very little.

I can confirm that, at least in some instances, SEP does NOT play well with windows 7 rtm.  I am not sure whether it is a conflict with the OS, some other VPN/networking software I have installed, or a combination, but it completely hangs the system on load until it is removed.

I am hoping very much that the latest version when it is released will truly support win7.  SEP is a great product, and I liked using it, but I have no choice but to leave it uninstalled until it is fixed.

I am running MR4MP2 and not having issues.   The trick is to just install AntiVirus and Anti Spyware.  If install anything more I was getting problems.

do you happen to be running any networking components like Intel PAN or a vpn like openvpn or NCP secure?  or VMware?  I tried installing just those two components, but the same thing happened.

I just did a fresh install of SEP 11.0.5002.333 (unmanaged mode without NTP) on a newly-created Win7 Pro (RTM) VMware Workstation 6.5 virtual machine.  Before loading SEP, I ran Windows Update and fully patched the OS as well as turned off Win7's firewall.  The install went smoothly although when the option came up to restart Windows, nothing happened so I restarted the normal way thru Win7's menus.  When the VM got past the normal POST, it hung at a completely black screen!  After waiting awhile, I reset the VM thru VMware's GUI after which the login prompt and subsequent desktop showed up just fine.

Previously, I had installed SEP 11.0.4202.75 on another Win7 Pro (RTM) VM and although I noticed some odd behavior with LiveUpdate, I didn't experience the same restart and forced VM reset problems like I had with the latest SEP 11.0.5 release.  Now I realize 11.0.4 didn't officially support Win7 RTM (only beta?) but these issues I encountered with a fresh OS and SEP install doesn't instill a whole lot of confidence in me where this latest SEP release is concerned.  I'm wondering if this same issue would've occurred on a physical box?  Anyone else try what I did and experienced this same behavior?
