Metronomic Cinema VST won't install

Using PC Cubase 7.5, Groove agent 4 they all work fine. Registered Metronomic that all went well. Downloaded it three times once on run two time on save. When it get’s to the install point after it’s unpacked and ready it just quits, and won’t install. What do I have to do. I’ve tried turning off virus checker also. Could it be because I registered the elicense before installing it?
