I am trying to invoke one executable by putting following line on command prompt. (I know I can directly invoke the exe but let's just say I have no other way to do this due to some restriction) 'cmd /C' 'C:Program FilesABCxyz.exe' -register='abc'itself It is successfully run. /C is parameter to cmd.exe. But when I do this 'C:WindowsSystem32cmd.exe /C' 'C:Program FilesABCxyz.exe' -register='abc'Gives me error The directory name is invalidAny idea why? And how can I solve this problem?

I have to use full path of cmd.exe. As stated by Stephan, the correct way of writing it is some of the following options 'C:WindowsSystem32cmd.exe' /C.' %comspec%' /c.The question is Why 'cmd /c'.

It works for the way the parser is interpreting the line.When the line is readed and parsed, 'cmd /c' is converted to execute the command interpreter with the /c'. ArgumentsSo it is executed as%comspec% /c '.This substitution can be easily tested set 'ComSpec=c:windowssystem32calc.exe'cmd /c' echo hello. Regarding the additional question of why the extra quotes are needed: this is described in the help returned by cmd /?, specificallyIf /C or /K is specified, then the remainder of the command line afterthe switch is processed as a command line, where the following logic isused to process quote (') characters: 1.
