Impossible to re-install Norton Internet Security 2011

I need to re-install my registered copy of NIS 2011 after a hardware failure last week.  However, all of my attempts to do so have failed so far.

 

All of my attempts to run the Norton Removal Tool have failed before completion -- i.e., have failed at the stage of processing all MSI's. all of the Norton files that were supposed to be deleted by NRT at the re-boot stage  are still on my disk.

 

All of my attempts to run the NIS 2011 installation file have failed at the re-boot phase, whether I choose to re-boot now or re-boot later.  In all cases the re-installed NIS 2011 causes my computer to fail to boot in the next boot cycle and all of the Norton files that were supposed to be deleted at the re-boot stage are still on my disk.

 

Neither of the above works in Safe Mode, either.  Both in Safe Mode and in ordinary Windows mode, there is a total failure to complete the re-boot process, and I am left with a system that does not have any anti-virus protection.

 

 

Does anyone know a solution to this problem?  The problem has been reported a number of times in the past, but I have not seen any "solution" that will work in my situation. .  What can be done to clean up everything so that it is possible to do a clean re-install?

 

Thanks.
