Just wanted to let you know that when the service account creation fails
in 8.3 and you *do* run the installer with administrator privileges, it
may be that you chose a password that was "too simple".
The installer of 8.3 simply outputs "The service user account 'postgres'
could not be created."
The installer of 8.2.5, on the other hand, using the same password,
outputs something along the lines of "Service account could not be
created - Password is too weak!".
After I used Roboform to generate a more complex password and used that
for 8.2.5, it installed fine.
Then I uninstalled 8.2.5 and launched the installer for 8.3 again, this
time using the same complex password I had successfully used to get
8.2.5 running - and voila, the install goes just fine.
Really too bad that the new installer does not specify why the creation
failed!
Hope this helps
