Now you have file extensions turned on is your customer.properties file really a customer.properties, not e.g. customer.properties.txt?
Can you post the file just in case it's something strange, then I can try it on a system of mine?
I'd try a few more things... delete the RAC folder, run the genregxml.bat again. Did that work? If not, try to log into the computer as a different user. Try it on a different computer. Any luck? That is all the ideas that I have left. If you can't resolve it with that, then it is time for Gtac to get involved.
I have installed a new instance of Teamcenter, 11.5 and I see it is working with no issues
Do we have to perform the same configuartion for every client machine to get it work on 4-tier or do we have any BMIDE approach to append custom release status next to Item revision?
Yes, you need to deploy the configuration to each of the clients.
For customers that have a lot of clients they normally build a client image, and push it to all their clients via whatever software distribution system they use for everything else, rather than going around each client individually.
I take it that we were unable to find a resolution to the issue with 11.4?
