plug in Nik collectie van Photoshop elements 11 naar Photoshop 23 importeren

The easiest solution is to use the original installer for the Nik Collection.

If you don't have the original installer, then you would need to go to

C:\Program Files\Google\Nik Collection

and create shortcuts to each of the (64-bit) plugins

and put them in

C:\Program Files\Adobe\Photoshop Elements 2023\Plug-Ins

What operating system are you using?

Do you have the free version of the Nik Colloction that was offered some years ago?
