How to get Windows 10 for free | How to install Windows 10: There is still a way to avoid paying…
I often read of people having problems with Norton products and I have just bought NIS 2006 and want to replace NIS 2004.
Should I completely uninstall NIS 2004 first or can I install NIS 2006 on top of it and retain the settings etc?
I have checked the documentation and Symantecs web site but cannot find the answer.
Thanks for your reply skyver I will probably do as you say but just wondered whether anybody had actually come across any problems. I probably worry too much!
I have just done it and had to Uninstall and do these things before I could successfully install.
Clear the Temp File in IE.
Make a Restore Point.
Otherwise all went well, albeit it took rather longer than I expected.
Now appears to be running nicely.
Just to clarify;
You say you had to uninstall and do the three things before you could successfully install. Do you mean you had to uninstall 2006 because you hadn't done the three things first and your installation failed or you had to uninstall the old system before you did the three things?
Sorry to split hairs but as you can see from my original thread I want to find out if it's necessary to uninstall the old system first.
Clearing the Temp Internet Files in IE.
Defraggging the Local Drive.
and I would recommend making a Restore Point first.
I cannot download Norton Internet 2006 or SystemWorks. The PC has done this previously without problem but I have been fiddling around with Registry Cleaners, & now problems have arisen. System works, half loads & then stops - NIS was stopping at Pixyl.Dll, but now will not even start to download - nothing at all. I have tried reinstalling, Live update etc. Even LU has problems as it will not download anti-spam & anti virus definitions/updates. Please help
I have always been a fan of Norton, but, after trying to install Norton System Works 2006 3 times I contacted Symantec and first of all they asked for screen shot when it failed, I sent these and received the following advice.

As I am not confident and don't want to follow all this advice I am returning the software.
I am running Avast AV with no problems and I will try a free firewall.
- I am in the 4th day of trying to install NIS 2006 from a download.
All looks well including the automatic activation sequence. But I then get a message from the Norton task bar Icon that the software is not activated and I am no longer vrus protected.
I have contacted Norton and await the arrival of their technical advice. Looking at Amazon I notice there are 158 reviews complaining of major problems with NIS 2006 - Amazon are rating
it 1 star - which means do not buy it. I have used Norton versions for 7 years - what on earth have they done with 2006?
