Have purchased Dell laptop with bundled software when I have tried to use this to update my desk top it says 'not Dell computer' as I have paid for this software I feel I should be able to use it on my other machine as this will keep them the same. Any suggestions?
Diodorus Siculus is right. As this is OEM software it can only be used with the hardware it was supplied with. You have not bought the software. You have paid for a licence to use it with the computer with which it was supplied, and only that computer.
Sorry but there is nothing you can do, except purchase additional licences.
