I have been trying to install Postgresql server on my machine (Windows 8-64 bit version) but it is failing to install by throwing the following error –

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

 

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.

 

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

 

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

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.

 

Thanks & Regards

You are getting these from where?

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