Two mysteries: A few weeks ago I installed Canon Print Studio Pro software. It showed up as a Photoshop plug-in and was available by clicking the Automate item in the file menu. It was unavailable yesterday and while searching for it, I found that I had two copies of Photoshop installed; Photoshop 2018 and Photoshop 2019. The plug-in did not show in either copy.
I was able to reinstall the Canon Plug-in into the 2019 version.

Can I delete the 2018 version without causing disruptions in my computer?

Any answers to the Plug in disappearance mystery would be appreciated.

Although not sure on this program the short answer is "yes" you should be able to delete, however if old versions are not removed at time of updates they both on occasion have been known to share same drivers. (Reason many programs ask you to remove old first).

However, here is a "trick" I use when in doubt. Just rename the old folder software resides, writing down old name somewhere, then reboot. After using new program for a month or more with no problems you are relatively sure you can delete old. If get error message you can rename old folder back to original.

Without access to your hard drive or installation actions can't answer Plug In first disappearance but guessing it was there somewhere.

Thanks. I totally forgot that old trick of inserting an "x" in front of application name in the folder. Actually,my computer has two older Photoshop applications in addition to the newer 2019 version. Much searching seems to confirm that older versions need not be kept on the computer. I will check to make sure all of my desired plug-ins were transferred to the new installation, and then will rename the "excess" files.

It depends upon your OS.. I have a windows 7 desktop I uploaded CC2019, and all was well until I tried to open a JPG!.. I contacted Adobe, and they were a great help, but rolled me back to 2018, as currently CC2019 will not as yet "play" with windows 7. BTW, I do not see any real advantages to upgrading to CC2019, so i'm not worried.. Windows 7 has been a great and stable platform for Adobe CC 2018!

That's what I've done, with no problems. Mac OS.

Pretty sure you are ok. However, post over in the post processing forum. I am sure they have opinions on this.

I did just this (delete '18 version) and it caused absolutely no problem at all. I use Windows 7 and use PS mostly to manipulate JPEG files.

I always put an X or something at the end as the Mac alphabetizes.

Most likely that the older programs ARE deleted and that when the new version was installed the old was deleted and only the folders with the path to where your plugins were stored are still there. This is so that you can move the plugins to the same exact place on the new install of 2019 PS. Then you'll have your plugins. If this doesn't work, as sometimes happens, then just reinstall the plugins as though it were the first time.
