I require a vba module/macro and userform written for powerpoint 2007/2010. This will form the basis of an addin for powerpoint. This is not a .com add-in. The required function is to act as a verification of a serial number or similar to register the add-in. I require an experienced developer who can advise on the best solution although I realise nothing is totally secure. I guess this would look for something unique to the pc Macid or similar or generate a random sequence/string written to the registry and some form of algorithm to provide a serial number. The xml ribbon menu would be registered on success (this should be provided also) and without the add-in registered the ribbon menu would be non functioning. This is an on going project and we and there will be more complex work required in the near future.

So, it means you need a VBA code which will read the CPU ID, when the CPU ID is matched, then your VBA code will activate the ribbon button. Otherwise it will disable it. All done within VBA code?
