so installed the program and trying to access to SPS but it keeps error E666: Access to Service Programming Server was denied.
Tried but failed:
installed it standalone also server database . many times but no use
need a New-Different “Safe” cable if you using USB —-> RS232…..

Normal TIS2000 software that comes with it requires a USB security dongle. Go figure. GM Software TIS2000 is COM yet the security is USB. This REALLY screws up things sometimes.
If you do need the dongle and don’t have one, it will come with error E666
