You are going to install the Real-Time Windows Target kernel.
Do you want to proceed? [y] : y
'C:\Program' is not recognized as an internal or external command, 
operable program or batch file.

Error in rtwintgt>RunInstaller (line 230)
    errmsg = regexprep(fread(logh, inf, '*char').', {'^Error: ', '[\n]*$'}, '');

Error in rtwintgt>rtwt_setup (line 112)
result = RunInstaller(prompt, 'install');

Error in rtwintgt (line 58)
  retval = feval(subfn, prompt);

Any ideas?

There seems to be a small bug in the RTWT installer in R2011b which causes problems when your MATLAB is installed in a path containing spaces. You can fix this bug yourself:

   >> edit rtwintgt

Find the that reads as follows:

result = system(sprintf('%s %s', installer, args));

and replace it with:

result = system(sprintf('"%s" %s', installer, args));

This adds a pair of double quotes around the installer path, so that when it is run using the System shell, there are no problems because of the space in the path.

Hi mam,

I tried what you suggested.

But still i am facing following error..

-------------------------------------------

>> rtwintgt -install

You are going to install the Real-Time Windows Target kernel.

Do you want to proceed? [y] : y

Error using rtwintgt>ErrorDialog (line 318)

Installer error: "Failed to start Real-Time Windows Target kernel service.

An instance of the service is already running.".

Error in rtwintgt>RunInstaller (line 239)

ErrorDialog(prompt, message('rtwin:installer:installererror', errmsg));

Error in rtwintgt>rtwt_setup (line 112)

result = RunInstaller(prompt, 'install');

Error in rtwintgt (line 58)

retval = feval(subfn, prompt);

Since the error says "An instance of the service is already running" - you don't need to start it again. Run "rtwho" and see what you get as the status.

Got the same error as @sriharsha. edited rtwintgt as suggested by @kaustubha. Again getting the same error as @sriharsha. Now i ran rtwho and got this- Real-Time Windows Target engine error: Real-Time Windows Target installation is not complete. Please type 'rtwintgt -setup' to complete the installation. Type 'help rtwintgt' for more information. Help!! ps-i am also using r2011b, because of my real time setup limitations.
