I have been trying to install Postgresql server on my machine (Windows

I searched some of the forums where the solution mentioned was to add an
environment variable “COMSPEC” with the value –
“C:\Windows\system32\cmd.exe”. I did this but the issue persists. Also,
there is no semicolon at the end in the value of COMSPEC variable.

See if the below helps:


I tried installing 2 versions of Postgresql but I am getting the same
error for both. The versions are as follows :

1.       postgresql-9.3.14-2-windows-x64.exe

2.       postgresql-9.6.0-1-windows-x64.exe

You are getting these from where?

Since the COMSPEC variable is present, it got me thinking if this is a
general exception thrown while installing postgresql.

But is it in the format shown in the technet article above, in particular the Data type?

Also, are there any pre-conditions to be checked before installing the
server. Could a particular software installation be hindering the
postgresql installation (At some forums, it was suggested that the
anti-virus uninstallation solved the issue. Could this be the reason?)

Please let me know how to resolve this.
