I often "call" Photoshop by typing CTRL-E to further edit Lightroom-managed images. I have discovered that the version of Photoshop that opens is PS CC 2015.1.2
I have kept up to date and the Lightroom just updated through Create Cloud is CC v2015.6 ACR 9.6. Lots of Googling and searching here does not highlight my exact problem but very similar issues happen in many versions. When I go to C;|Program Files\Adobe\Adobe Photoshop CC 2015\photoshop.exe I find a file that reports itself as dated 1/13/2016 ("Last modified"), is only 135MB, and was last accessed February 15th
I looked at the prefs file and see no joy for checking the path of the "call". I have restarted my computer since the CC update of Photoshop, Lightroom, and Bridge to 2015.6
I have been a Creative Cloud subscriber for a long time.
A search of my whole computer reveals only one "photoshop.exe"
The latest version of Lightroom is 2015.6.
The latest version of Photoshop is 2015.1.2.
So LR is opening the latest version of Photoshop.
