Error SQL INSTAL

[Oberdan]

When installing Postgree near the end of the installation, the following error occurs:

"The SQL DatabaseServer 8.3 '(pgsql-8.3) can not be installed. Ferivique to you in sufficient privileges to install the service system."

This behavior is often the result of an overzealous firewall or antivirus program, please check our Firewall Troubleshooting Guide and if you use any of the programs listed there, follow the steps listed.

I use the Vista system, and it came with Norton Internet Security, but not set up, I think he acts resume partially, so I downloaded Avast! Antivirus. In this case the link for which the guidelines should I follow?
Thank you very much

[kraada]

Avast should not need any special setup, just make sure that Norton Internet Security is completely uninstalled.

[Oberdan]

Norton Internet Security is not installed COMPLETELY istalado.Não because he knew he would have to pay, is this true? Should I uninstall the active part of Norton?

[kraada]

Especially if you are going to use Avast! instead, you should definitely completely uninstall Norton. Running two anti-virus programs will slow your computer down quite unnecessarily.

[Oberdan]

Well, uninstalled Norton, and now that the procedure, which the link u Firewall Troubleshooting Guideque should I follow knowing that only use Avast?

Thanks

[kraada]

Now that Norton is uninstalled, PostgreSQL should just install properly.

[Oberdan]

In fact the conclusion that is such a PostgreSQL stackbuilder & Enterprise, which seeks to up grade to Postgree v8.3.5, and then at the end of the heating installation is error I mentioned at the first post. And even without the Norton continues.
