 PostgreSQL version: 8.3, 8.2
 Operating system:   Windows Vista Ultimate
 Description:        Can not Install PostgreSQL - error at the end of
 installation
 Details:

 I try many times to install PostgreSQL 8.3 and older versions on my new
 mobile computer Acer AS7720G-933G64Bn with installed Windows Vista Ultimate
 OS. Unfortunately it is not possible. In the beginning I have one error.
 After User Account Control (UAC) disabling the error is changed to "Failed
 to create temporary directory." on "Initializing database cluster (...)...".
 I can apply the  log file of installation if you tell me how and where?

 Can you give me some idea how to solve that problem?
    

It's possible you've hit one of a couple of Vista-related bugs that
we've found very recently. There is a test build at
http://developer.pgadmin.org/~dpage/postgresql-8.3-vista-fixes.zip if
you wish to try it. The changes there will be rolled into the next
official build.
