the download version instead of the installation disk.
Get Norton 360 v4 from: https://webdl.symantec.com/?SASSERVER=lcsitemain.symantec.com&TRANSID=%2f23686635%2fB8bePX13VSPPF007J%2fABUG003M%2f%26%7e%2f%26%7e%2f%26%7e%2f%26%7e%2f%26%7e%2f%26%7e%2f%26%7e%2f%26%7e%2f%26%7e%2f%26%7e&LNG=ENG
The advantage of installing the program using the download version is you will have the latest installer that may have fixes to known issues since the installation disc was released or received by you.
We have four computers. Three are IBM/Lenovo Thinkpads that originally had XP PRO and have had all updates intalled on them from Microsoft and have been upgraded to XP SP3. I've installed Norton 360 on all three. Two originally had Norton 360 V3 on them and were upgraded to Norton 360 V4 with no problems. One had Norton 360 V4 directly installed on it with a newly purchased Norton 360 V4 CD.
Since Norton 360 V4 worked so well on the three Thinkpads, I elected to install the Norton 360 V4 CD on a Lenovo desktop PC we have. The Lenovo desktop came with XP Home Edition but has been upgraded to XP SP3. Since the desktop has mostly the same software on it as the three notebooks, I didn't expect any problems.
I got through the Norton 360 installation process as far as bringing Norton 360 up and requesting a definition update. The system then started telling me some of the XP Home Edition files needed to be restored from my XP installation CD. I couldn't get out of this process no matter what I did. Reboots resulted in many of XP's functions being disabled.
I feared that I would have to re-install XP and start from scratch installing software and file back-ups! I desided to reboot into Safe Mode and elected to remove Norton 360 V4 from the system. Thankfully, the system returned to normal after I removed Norton 360 and booted to normal mode.
As far as I can see, the major difference between the three Lenovo notebooks and the Lenovo desktop is the notebooks originally had XP PRO that had been updated to XP SP3 and the Lenovo desktop had XP Home Edition updated to XP SP3. What gives?
