The re-PostgreSQL error has occurred: Problem running post-install step. Installation may isn't complete correctly. The database cluster initialisation failed.

The following is their own reload after the problem has been found in the blog park inside the solution, however, in accordance with this method or can not solve the problem, finally in the final resolution, fool-type error, again prompted: Please close the antivirus software and firewall.

Previously normal use of PostgreSQL, the problem today: reported *.dll error. Baidu a bit, can only reinstall.

During the reinstallation process: Problem running post-install step. Installation may isn't complete correctly. The database cluster initialisation failed.

See online workaround for--Reload PostgreSQL and select "Chinese" or "Chinese,macau S.A.R" when selecting "Local". Instead of the default. I see this method and the result is unsuccessful.

So continue to try, find Niang. Finally successfully resolved, a variety of attempts to pay a great deal of energy, here to share, hope to use less go some detours.

①: Enter cmd-net user (function: View user): Check if there is postgres this user, if you have but do not remember the password, then change the password, if not, create a postgres user.

②: Uninstall the installed program. If there is a need to delete the registry in relation to PostgreSQL (I deleted them all), you can enter Regedit by typing in "run", in HKEY_CURRENT_USER and Hkey_local_ Software in the machine in the relevant PostgreSQL deleted AH. Of course, it is better to clean up the rubbish for the sake of insurance.

③ the new installation directory in a different location. For example, E:\postgresql, as long as it is not previously installed in this directory PostgreSQL can be. Of course, if you want to delete the previously installed directory, "Clean up the trash" in the "Computer Manager", and then re-create the directory in that location. Then I can tell you not to do so, because it is not possible, I have tried many times to fail to tell you not to do so.

④: The reinstallation begins. Of course, run as administrator.
A: If the installation is not error-free, then congratulations. My step to this is solved.

B: If there are error prompts also no problem, install directly, pay attention not to uninstall, specific reference: http://www.geekscribes.net/blog/2009/04/22/ postgresql-database-cluster-initialisation-failed-solution/.

I am using the windows7 system. Do not know if the other system solutions are applicable
