Well I can answer part of the question - I found that a 30 day trial exists on the Symantec site, so I downloaded it, and it installed fine. However, upon reboot, it requested and ran LiveUpdate. It downloaded a Norton Ghost file 7065.9KB fine, finished decompressing it fine, but on install I got a dialog box "Fatal error during installation".

It gave the errors as LU1812; A program that was part of this update failed when it ran. The update was not applied. For this one, I clciked the LU1812 link and ran the script test. It said "Operating system not supported", then it brought up another web page and said there is no 1812 in the Log file, so it must be an intermittent error. Sweet.

also reported LU1806: LiveUpdate downloaded all of the updates you requested, but all of them failed to install. Please try to get the updates at a later time.

For the 1806 error, it suggested I run LU from Control Panel. Bu then Ghost popped up,  I think for the initial run? Anyway, now it shows an error "The feature you are trying to use is on a network resource that is unavailable."

I remember years ago stopping the use of Norton Utilities because LiveUpdate never worked reliably. So far this experience has been pretty ugly, it feels like no one uses this on XP x64. I will likely stop using this unless I hear from someone that x64 is fully supported, since it's not mentioned on Symantec's site. Thanks.

I guess I have gotten my answer doesn't seem like this is the product for me...

OK, I'll keep any eye out for ShadowProtect's 64 bit version. Thanks!
