Elements 14 re-installation

My old computer died and I got myself a new Lenovo Ideapad 310, which apparently is a 64-bit system, with Windows 10 Home Edition pre-installed. 

I managed to re-install PSE9 and got it working, but I failed to get the PSE14 (which I purchased on 25/12/2015) to install.  The error message was something like "this 32-bit application cannot be installed on the 64-bit machine".

So what do I do now?   Why is it that the PSE9 can be installed and not the PSE14?

Am not sure if I should or can download the 64-bit version of PSE14, and install it with my present serial number.  I think Adobe will not permit this.  I hope I do not have to pay one more time for PSE14

Would any kind folk please advise.

best regards,
