Обсуждение: BUG #14022: Installer fails complaining about COMSPEC but COMSPEC is correct.

The following bug has been logged on the website:

Bug reference:      14022
Logged by:          Mehmet Sinan Hasanoglu
Email address:      shasanoglu@gmail.com
PostgreSQL version: 9.5.1
Operating system:   Windows 7 64 bit
Description:

I checked comspec and it is correct. I double checked with

%COMSPEC%" /C "echo test ok

and everything seems ok. However installer (both 32 bit and 64 bit) fails
with the message:

There has been an error.
The environment variable COMSPEC does not seem to point the cmd.exe or there
is a trailing semicolon present. Please fix this variable and restart
installation.

I am attaching the installer log too:
