Dec 14, 2011  Application not found When I click on regedit in the C: Windows folder I get an 'Open With' window. The same window pops up when I try and open anything on.

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)

itself It is successfully run. /C is parameter to cmd.exe. But when I do this

Gives me error

Any idea why? And how can I solve this problem? I have to use full path of cmd.exe.

Try this instead:

For example:

As stated by Stephan, the correct way of writing it is some of the following options

The question is Why 'cmd /c' .... works? It works for the way the parser is interpreting the line.

When the line is readed and parsed, 'cmd /c' is converted to

looks for a file named C:WindowsSystem32cmd.exe /C.

Regarding the additional question of why the extra quotes are needed: this is described in the help returned by cmd /?, specifically

If /C or /K is specified, then the remainder of the command line after the switch is processed as a command line, where the following logic is used to process quote (') characters:

So, if the first (non-whitespace) character of the command is a quote, you need an extra pair of quotes around the entire command.

Additional note: combining MC ND's answer with mine, the first command line in the question is being interpreted like this: we start with

which becomes

due to the rule that replaces cmd ->%ComSpec% combined with the bug/feature that discards the extra quote mark; this then becomes

because of the rule that removes the first and last quote marks when processing /C.

The Win32 file system rules discard the extra backslash, so the executable launched is

and the executable is presumably ignoring the missing close-quote in its argument.

Strange it seems :/

This works. Don't know why. May be the double quotes before and after 'C:Program FilesABCxyz.exe' -register='abc' are required. Wish if someone will explain that.
