Transferring Photoshop Elements App to New PC

As I understand it, the Microsoft Store does not issue serial numbers.  Your Microsoft account authenticates that the software belongs to you.

Here is the official Adobe FAQ about purchases from the Microsoft Store.

Hi Ashley.  The Microsoft Store (and the Apple Store) versions have some differences from the one purchased from Adobe or other third party sellers.  I just had a chat with an MS Store support person and they told me that you are only allowed to install the MS version on a single computer.  For that reason, I assume there is no need to sign out of one computer to sign into another.  I asked the chat person how to transfer the program from one computer to another and was told that you have to sign into the new computer with your Microsoft account. 

As you may have seen from another post today, Microsoft told a user to contact Adobe Support.  It is my belief that is wrong, but I am trying to seek confirmation from Adobe.

From what I can see, there is no good reason to purchase from the MS Store.  Updates to the program are delayed and now what I have just learned from MS chat gives me another reason not to recommend that method of purchase.  Things may be a little different with the Apple Store because I thought that the program can be shared on more than 2 devices.   But, after reading several pages on the MS Store website,  I'm not convinced that is true either since references go back the Adobe license.

My advice to you is to contact the MS Store support and let them walk you through the process.  If you find anything different than what I am saying here, please report back to this thread.  Thanks.
