Question

I\'ve been trying to install the 64bit version of PostgreSQL 9.2 for Windows on my machine (Windows 7 64bit) and get this error:

The environment variable COMPS

Answer 1

Very easy fix:

1. Just open Advanced System Settings in Control Panel and create a new System Variable( in the System Variable instead of User Variable section).

2. In the variable name, enter ComSpec and then in the variable value , enter C:\Windows\system32\cmd.exe.

Alternative fix:

If you have already the ComSpec variable in the System Variable section, remove the ;at the end of it this should fix it.
