Query: Very hard to install

It took about 15 hours per machine over a week period go get Norton AntiVirus to install and activate. Had to send a lot of emails to Symantec Tech Support. Most responses did not work, and required one to almost be a super administrator to understand what all had to be done, such as registry edits, customizing startup with msconfg, and understanding directions that did now work as Symantec said they would. Then after 4 days, one of the AntiVirus installations stopped working, requiring another 8 hours to re and re and re-install.After installed, it worked. An incredible time consuming product to install.
