app data is a hidden system folder, its nothing to do with admin rights. you will need to open file explorer, go to view , show hidden items (win 11)
or view show hidden items check box in the view options
then go to users / yourusername/ and you will see appdata at the root or in a folder called default if you have more than one account on the machine.
I think its then appdata/localpackages/serifeuropelimited

to anyone using an old gpu that has cuda cores, but is randomly no longer able to tick hardware acceleration - this may be a way to force gpu acceleration :
change settings/performancepreferences file in notepad from false to
<UseHardwareAcceleration>True</UseHardwareAcceleration>
you will also need to install openCL from windows store and it helps to install the cuda drivers (the old way) not the nvidia (you must buy a new GPU because we dont like your old cuda cores) 'experience' way.
or serif could just let us tick the box in preferences when we all moved to win11 and lost all gpu support...tut tut
