Hi,
This is what I would try:
First, make sure that you are logged in with an administrator-level login.
Second, reboot the computer and try the install again.
Third, ensure that you do not have any copies of any version of SQL installed (and showing in add/remove programs).
Forth, try installing again.
Finally, check to ensure that you have the correct connection protocols (TCP/IP, Named Pipes, etc.) enabled and that your firewall (either a physical one or Windows Firewall is configured to allow traffic in on port 1433)
With regards to error 26 -- were you getting that from SSMS (management studio) or from an application that is trying to connect to it Was this on your local machine or a remote one
