Quickbooks Desktop Pro 2016

Okay - So I have a brand new PC and have installed all software which I previously had with no problems.....EXCEPT QUICKBOOKS !

So I have paid for and legally own the Desktop Pro 2016 software and should be allowed to use it. However, it will not for the life of me register my software despite having all browsers (IE, Chrome and Edge). I have also tried the Quickbooks Tool Hub. Support is impossible to get hold of. All I need is to be able to activate my product, seriously you would think I was asking for the safe number for the bank of England!

Any tips would be so gratefully appreciated.

Thanks
