Catastrophic failure whilst installing sdplus

Catastrophic failure whilst installing sdplus

      Was trying to update an old instance of our sdplus application following these guidelines. 
https://www.manageengine.com/products/service-desk/on-premises/migration-sequence.html

We were originally on version 9334 using mysql which was the default when we first installed service desk plus a few years ago. 

I was able to upgrade to 9336 without any issues. 

However when i tried upgrading to the next step which was to take me to 9400 i was informed i could not continue as i needed pgsql. 
 
Found these instructions here called How to move from Mysql database to PGSQL database
https://www.manageengine.com/products/service-desk/on-premises/faq/upgrade-installation-backup.html#pgsql-database

Followed instructions, performed database backup - completed successfully .
Uninstalled old 9336 instance and downloaded new 9336 full version found here http://archives.manageengine.com/service-desk/

As soon as the install begins to happen i get the below error. 

Nothing is written to event logs and nothing is written to the default location Manageengines in C:

Any idea?
