you are installing MATLAB offline with the File Installation Key, and the products are missing, make sure you have the correct key.
For instructions on obtaining a new File Installation Key, see this related article: Where can I find the Activation Key or File Installation Key (FIK) for my license?
NOTE: Starting as of MATLAB R2010b, there are two files for each product.
You will need the .common file as well as the 32/64-bit file (win32/win64).
The easiest way to resolve this is to download the files again, and run the installation again.
This issue could also be the result of a corrupt or incomplete download of that file.
In any case, you will need to obtain a copy of the file for the product you wish to install in order to install it, and those files must be placed into the same directory where the installer itself resides, or was extracted to.
Instructions on how an Administrator can download the ISO for your release can be found here: How do I download the MATLAB . and earlier: Windows: If you have downloaded the installation files, make sure there is a corresponding file for each product (ex: MATLAB78for MATLAB).
If you are missing the files for any product or if the files have been extracted, the installer will not list those products to install.
