Unable to update Adobe Photoshop Elelements 2021

@MajorBlixem, Are you uninstalling from the Control Panel? Are you getting the Error 87 error code when you try to uninstall even after a reboot of your machine? If so, open Task Manager, and click on the CPU header.  This will sort running processes by how much CPU activity the process is taking up. 

Try to End Task for all active processes that may be interfering with the installation.  Don't end Windows Explorer.  Hopefully, this will allow you to uninstall the current program.

I'm sorry my earlier link took you to the Elements 2020 download.  You just needed to scroll up the page to find the Elements 2021 download.  But here is a direct link to the Elements 2021 download.

I have a similar issue. Running P Elements 2020, Ver. 18.0.

"Update" is grayed out. 

I have two printers, a Canon color injet for photos and a BW laser. I can print Word or print test on both, but if I send a print job from elements to the Canon, the BW laser taks over and prints a BW photo on the laser.

Should I also install and reinstall P Elements? Are you aware of other potential issues?

The comment from the adobe employ is quite accurate:   I had to stop 3 things from downloading and installing when I was downloaded photoshop--- it also downlaods lightroom, and bridge, all apparently "in the background", and m ycomputer didn't like that going on.    

Is there any other CC app installed on your machine.

If yes, then there might be another update running in background for that application.

You can simply launch creative cloud desktop app and see if any update is running.

If yes, then wait for that update to finish and then start the update for Photoshop elements.

Hope it resolves the issue you have been facing.

How did you try to update?  Were you given a choice in the Editor to update now or upon exit?  If so, which did you choose?

Your best bet is probably to uninstall your current program and download and install the latest version from this link.
