MATLAB: Real-Time Windows Target: rtwintgt -setup claims to be ‘successful’, but rtwho then reveals that the kernel hasn’t been installed.

rtwSimulink Desktop Real-Time

Hi everyone,

When I try to install rtwintgt, this occurs:

================================================

You are going to install the Real-Time Windows Target kernel. Do you want to proceed? [y] : y The Real-Time Windows Target kernel has been successfully installed.

>> rtwho Real-Time Windows Target installation is not complete. Please type 'rtwintgt -setup' to complete the installation. Type 'help rtwintgt' for more information.

=================================================

Can anyone shed some light as to how I can get the setup working properly??

I'm running MATLAB r2012b with Real-Time Windows Target 4.1 included on Windows 8 64-bit.

This is a known problem with R2012b and Windows 8. This is caused by a late change in Windows 8 that prevents correct initialization of the real-time kernel. Unfortunately we haven't been able to fix it for the R2012b release.

Please try R2013a Prerelease, the problem should be fixed there.

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.
