> Description: Install Error
> Details:

> I am trying to set up a test environment which requires PostgreSQL version
> 9. I am getting this error "Unable to write inside TEMP environment variable
> path." when using the OneClick installer for Windows. After a lot of
> research it appears that this error is most likely the result of the
> antivirus software running on my machine. Unfortunately, the system being
> used is government owned and well locked down. I have been completely
> unsuccessful at disabling or removing McAfee to allow for installation. I
> was able to use the pg_installer to load PostgreSQL v 8.2.21. Is there any
> way that I can get version 9 packaged similarly to allow for installation or
> is your development team aware of any other kind of workaround?
