Matlab hardware support package offline installation error

I am running matlab R2014a on windows 7. I am trying to install a directsound support package offline. I have gotten the compressed zip files from a mathworks technician. When I run the installer through matlab and select, "install from folder", after selecting the folder that the zip files are in and clicking next I get the following error, "C:\Users\mstarkey\Documents\DS does not contain any support package files.

 Specify a folder or subfolder that contains support package files. These files use the following
 naming convention:
 [name]_[release]_[version].zip"

When I select the folder with the zip files through the installert, the zip files do not appear in the folder. It looks as though the folder that contains the zip files is empty when viewed in the installer.

I've attached the folder that I am trying to access.

I have the same error when installing 'support hardware packages' from the internet or from the local directory. I have to do this on with a Matlab 2014a(32bit) on Win7 64bit.

Any ideas are very welcomed.

Best regards

Frederik
