Greetings @agangaiah,
There are two possible causes of this install error:
1. Following up on what we discussed, we determined the cause of the failed installation and licensing issues you were encountering was related to a conflict between the ThingWorx platform install and the Manufacturing Apps Express installer.
This leads to a key point that is often overlooked by users going through the initial installation:
The ThingWorx Manufacturing Apps Express installer is for use on a PC where the ThingWorx platform has not already been installed.
If the ThingWorx platform is already installed, the ThingWorx Manufacturing Apps should be imported as an extension directly into the platform.
To locate the Extensions download, open the PTC Software Download Page and expand the following folders:
PTC Smart Connected Applications | Release APPs | ThingWorx Manufacturing Apps Extension | Most Recent Datacode
2. The other cause of this problem is related to a conflict between third-party security software and the ThingWorx Manufacturing Apps v8.1. The PostgreSQL install scripts were prevented from having the correct permissions to complete. This conflict has been addressed, starting with the current release of the ThingWorx Manufacturing Apps (8.2).
Best regards,
Steven M
