I bought Elements 2018 in August 2018, Adobe says it's 64-bit, but when i try to install it on a new macbook pro (64-bit) the info for the app says it's 32-bit. Surely I don't have to buy a new version?
A new Macbook needs new apps. 64-bit is just one small part of this, the only part reported by the press. This needs to be included in the budget when getting a new computer.
Moved to the Photoshop Elements forum, from the Photoshop forum.
Items of 2018 are not 64 bit. So since adobe does no updates to elements versions after the new version s realeased (yearly) this was never fixed.
On Calatina or newer, only versions 2020 and 2021 of Elements will work.
So if you want to use elements on MacOS >catalina, then yes you have to buy new (or look for software that is better supported than elements. For only editing, i would have switched already. )
