Here is the client Pack (x64) It also notes that they support SQL 2005 on x64 which many people have posted asking about. http://seer.support.veritas.com/docs/282644.htm
I have some windows2003 64bit on AMD 64 hardware. If this is only a patch, what agent should I install before the patch? I didn't found any agent I could install. Only the 5.1MP4. I would appreciate any help!
Actually, This is the FULL client install for x64. I just installed it on a few of our x64 based clients and it is native 64bit code. It is kind of messy about uninstalling the old client so you might want to do an uninstall first.
