Correct quoting for cmd.exe for multiple arguments

The machine must have one or both of the most recent versions of the .NET Framework installed (either 3.0 or 3.5 I'm not sure which introduced sqlmetal.exe).

Additional information is available on MSDN:

The SQLMetal file is included in the Windows SDK that is installed with Visual Studio. By default, the file is located at drive:\Program Files\Microsoft SDKs\Windows\vn.nn\bin. If you do not install Visual Studio, you can also get the SQLMetal file by downloading the Windows SDK.

Your problem is most likely that the shell does not know where to find your make program. If you want to use it from "anywhere", then you must do this, or else you will need to add the full path each time you want to call it, which is quite cumbersome. For instance:

"c:\program files\gnuwin32\bin\make.exe" option1=thisvalue option2=thatvalue

This is to be taken as an example, it used to look like something like this on XP, I can't say on W7. But gnuwin32 used to provide useful "linux-world" packages for Windows. Check details on your provider for make.

So to avoid entering the path, you can add the path to your PATH environment variable. You will find this easily. To make sure it is registered by the OS, open a console (run cmd.exe) and entering $PATH should give you a list of default pathes. Check that the location of your make program is there.
