NIS 2011 will not install!!!!

5 days ago, i started getting error msgs for various tasks related to other software, that the symantec shared folder was corrupted.  I could not open the folder and got "unaccessable" and "corrupt" messages again.

 

A Norton Tech cleaned my system using Norton Removal Tool, and then tried reinstalling NIS 2011.  It would not install.

 

I've been helped in the last 5 days by 3 different Norton Techs, and each time after using NRT and Norton Power Erasure, NIS will still not install.

 

Last night I was transfered over to a Manager Tech.  He went through my registry and deleted all Symantec registries.  After reboot....my OS would not load.  I had to put the install disc in and "repair" it!!!

 

I have run NRT and NPE numerous times and have tried NIS 2011 re-install numerous times (even disconnecting internet connection)....and still NO INSTALL!!!

 

What is going on?!?  Why won't it install?

 

I am still waiting for another Tech to contact me to try again...

 

OS - Windows Vista SP2
