arduino support package matlab 2015a error

Hi!

I have some problems with the Arduino Support package, every time I open Matlab I have to download and install it again. After the installation it works properly until I close Matlab and open it again then it says that I have to download the support package to use these features. Any ideas? I am using Matlab 2015a and Arduino Leonardo. Thanks a lot.

You might need to Run As Administrator once, if you do not have proper write access to a directory.

Another possibility is that you have something in startup.m or finish.m or pathdef.m that is overwriting the path so that it loses track of the package.

A third possibility is that your Add-Ons directory has been corrupted. If that happens, then you have to uninstall all of your add-ons, remove everything from the directory that MATLAB uses to store the add-ons, remove everything in the download cache, and then reinstall all of the add-ons. (This is the procedure Mathworks sets out. I would say that the situation cries out for some good package management tools!)

Thanks for the tips, a brute-force reinstall solved the problem! :)
