Although I did the installation two times exactely the way the manual says the dataserver failes to start. I don´t have another idea so I ask you guys. Don´t be surprised to read the word "update" in the error message, it appears because I tried to reinstall the dataserver.
After installing the first time without ssuccess I deleted all parts of the installation and cleaned the registry.
Maybe you can give me a clue? BTW: "Der Name für den Dienst ist ungültig" means "the name of this service is invalid" Thanks for any idea.
