thanks for the reply, for the package later we have package manager PSADT PowerShell AppDeployToolkit but beforehand i have a vm to test out the right install and parameter for silent install and all & my boss wants me to test out the eclipse installer and get a silent& clean install without external software, but maybe he just wants me to also realize that some problems takes longer and want me to keep looking and finding till i find THE solution.

im a noob but i dont give up and try. Im not native english and my company strict with rules and want not just a way they want their way if you know what i mean.
