The way which has worked for me:
- Install the Hardware support from the Add-ons button in Matlab and wait for the error. Once you get the error cancel and exit the installation.
- Now go to the directory shown in the error message: C:\MATLAB\SupportPackages\R2013a\downloads\arduino-1.0-windows.zip
and replace the existing corrupted arduino-1.0-windows.zip with the new one downloaded recently
- Disconnect internet connection and again go to Matlab add-ons and try again to install arduino hardware support package It should work this time.
