RT-Events Help file does not open when clicking on the help button

Question

when I click on the help button of a RT-Events block I get the following error message :

" 'cmd.exe' is not recognized as an internal or external command, operable program or batch file"

How can I workaround this ?

Answer

This problem occurs when you are using Windows 7 64-bit with Matlab 32-bit. There are two different type of 'cmd.exe' : one for 32-bit and one for 64-bit. Matlab is using cmd.exe command for opening help file, but cannot recognize the 32-bit version.

This can be solved by adding "C:\Windows\system32" in the environment variable PATH.

Key words : help cmd.exe Windows 7
