Hmmm maybe kosh scripts are not working correctly in 9.6 CT as they do in 9.5. Maybe PMOD can be solution to this, but it requires to rebuild my installer to use PMOD, and it's a lot of work. Shall see... because Kosh naranek is usually releasing new stuff once the official client is released, so we might have to wait a bit, unless our "eastern partners" fixed it somehow....
