until now, i always opened the project in Delphi and installed it there. But yes, i also tried the "msbuild" way. But there i got the Error "no target selected" when i execute it. I've to confess, that im not very familiar with the msbuild tool and i dont know if i'm missing some parameters or something. But when copy the text with the mentioned .proj file i always get this error. "Error MSB4040: The project doesn't include a target" (I translated it from German so sorry if it doesn't fit perfectly to the original English Error Message). Thanks for any help
i found my problem. I had to call th rsvars.bat immediatly before i call the msbuild. I thought it would be enough to call it once but i wasn't supposed to close the command prompt.
