5. In the Run dialog box, type the following text:
regsvr32 %windir%\system32\msxml3.dll
6. Click OK.
7. If you see the message "DllRegisterSever in C:\Windows\system32\msxml3.dll succeeded", go ahead with running the Norton removal tool, and reinstalling Norton 360.
Sorry for the time to answer but been quite long to actually uninstall everything and put it back.
Unfortunately it did not suceed. Have still the same errors, even though did exactly all as you advised.
I'm thinking about re-installing my previous back-up of the system but this is just sureal to have to come to this when all my softwares are working perfectly besides Norton...
I wouldn't call the problem 'solved' but I do think you have ended the dialog on trying to solve this one. Please do me the favor of clicking on the message that was most helpful to indicate to others that this thread issolved/closed/ended. It's only housekeeping but it does make things easier when you're scanning for places to assist users.
In this instance, the solution button probably isn't the way to go. It would erroneously indicate on a search that a solution was found, which isn't actually the case.
I have only seen two occasions, including this one, where it was simply not possible to install for one reason or another. It does rarely happen.
