Installation problem

Hi all,

I just downloaded the latest version of Grasshopper for rhino 5.0. When I run the "grasshopper_0.9.76.0" a dialog box appears with the next message:

"This package is not compatible with the rhino installer engine. 

DEVELOPERS:

For information on making you plug-in compatible, visit 

http://wiki.mcneel.com/developer/rhinoinstallerengine/overview"

I entered to this link above but i cant solve this issue. 

Does somebody knows what should I do?

Anyway, thanks in advance,

Diego
