fill the form in
then check your email if you've got the license
then copy and paste the license into the installation

then create your own password
then click next
click install
then it has the part where it says error opening file for writing.....
you click ignore
then go to manually reboot later
go to start
go to all programs
go to where it says blue coat k9 web protection
go to uninstall
click yes
then type the password that you made before
