Installing PostGreSQL - 2

I  am trying to install PostgreSQL from 'postgresql-8.3-dev1.exe', but the installation terminates with an error message saying that it could not create a file,
Here is the last bit of  'postgresql-8.3-dev1.txt ', it just might mean something to you 'cos it does not mean anything to me.
