P: unknown error while writing metadata to this photo

Hi Giorgio,

I realize this post is from earlier this year, but did you find a solution to get your Wacom functioning with Photoshop again? The trouble with most of these is that it may be a driver issue or we aren't seeing the behavior here. Would you be interested in doing a screen share with an engineer to troubleshoot your issue? 

Thanks,
Hannah

Soooo... bringing this post back up. Did this ever get fixed? I've only just today had reason in my line of work to open photoshop and attempt to sketch something up, only to find that this issue seems to be persisting months later in version 19.1.6 with an intuos pro small. Is there an actual fix coming for this...?

I had the same issue on my HP Spectre since the last update. MUST Uninstall the WINDOWS Update and TURN OFF the Auto Update option. Its a little tricky finding the damn thing, but for now PSCc is working normal again with my Wacom Tablet. 

Go to your wacom properties select mapping unclick the windows ink then go back and make sure photoshop is selected in the application.

thank you, but i did add the config  as described and worked ok  fine for intuos pro table but after half an hour tablet stopped working ,tried everything all over again nope its been returned ,new products should not have these issues.Everyone blames windows or mac but the real issue in the end is wacom.

for my old wacom intuos 3 this has been working for me:

Add a .txt in the Photoshop files

Wacom tablets : add a .txt file containing only “UseSystemStylus 0” (without the quotes) and name it “PSUserConfig”. Then place it in the following folder :

• For Windows : C:\Users\[user name]\AppData\Roaming\Adobe\Adobe Photoshop CC 2015\Adobe Photoshop CC 2015 Settings (Or select your Photoshop Version if it’s an other one)
• For Mac : Users/[user name]/Library/Preferences/Adobe Photoshop CC 2015 Settings

i bought one 3 days ago and returned it, it had so many intermittent issues would stop working,pen would stop ,brush size would automatically expand and contract ,would not be recognized ,uninstalled reinstalled driversused the config thin worked for 15 minutes /would not turn on,when using pen stylus with brush it would blob  out color/after 24 hrs  that was it for me a go back to using my logitech mouse,i cant believe an industry leader in the field like wacom would make garbage like this.
oh yeah tried one of their cheaper  intuos draw and will return it tomorrow  as its junk too?had a graphire and never had this issues.
Guess when technology companies get so huge they don't care about the customers,hopefully the competition will surpass Wacom with a superior product.

I just installed by brand new Wacom Intuos Pro yesterday, and it was working fine until an hour ago when I updated Adobe Photoshop, so the issue is obviously not fixed. Any ideas?

there are still problems after the upgrade. with the windows INK enabled, the feather pressure works, but the ALT + right click does not work. When Windows INK is turned off, the feather pressure does not work, but the ALT + right button works.
