How can I change the version of Photoshop opened by LR?

[Bazsl]

If I have both Photoshop 22.3 and Photoshop 21.2.6 installed, how can I change the version of Photoshop that LR uses when I open a photo in Photoshop? For example, if I open the selected photo in PS from LR and the photo opens in PS 21.2.6, how do I change LR so that it opens the selected photo in PS 22.3? Thanks.

Try un-installing and re-installing 22.3 using the CC Desktop App. This  may reset the Lr<>Ps link default to 22.3

When Photoshop 22.3 is the 'Default' Photoshop that Lr-Classic is linked to-.

You can add Photoshop 21.2.6 as an Additional External Editor Preset in the Preferences dialog.

It's use has-

Limitations:  You cannot 'Open as layers'. You cannot 'Open as Smart object'

Advantages:  Allows you to 'Open in 21.2.6', Allows you to set JPG as a alternative to TIFF or PSD in the default Ps.

I just found an article by Adobe that explains how to edit the path used by Lightroom in the registry. https://helpx.adobe.com/in/lightroom-classic/kb/edit-photoshop-command-missing-photoshop.html
