Kodi not starting

I have an older PC connected to my TV that I use for watching videos etc. It is an old amd athlon running win 7 ultimate with 4 gigs of ram and a decent gforce card.

I downloaded the latest version of Kodi and installed it without any issues. But when I try to run Kodi nothing happens at all.. There isn’t even an error message..

I am an IT engineer with over 16 years of experience in the field and this is what I have tried so far:
I have removed an reinstalled the program and cleaned the registry… Same problem!
I have tried running as admin.. Same problem.

I can’t figure out why it isn’t starting.. The PC in question may be old, but from what I have read, it should be more than able to run the program..

I’m pretty sure it’ll run on one of my newer machines,but I need it to run on the machine in question, as it is permanently connect to my TV for such purposes. It is rather inconvenient to connect one of my other machines to the TV every time I want to watch something.

Please can some one help me figure out what to do, as this is getting rather irritating. Any suggestions are welcome.

Thanks Ian
