>> ITDOES OPEN WITH ALL THE LR EDITS PRESENT BUT WITH A .tiff EXTENSION!
As a final twist LR immediately writes an "edit" copy of the .tiff version directly to the hard drive with no warnings of any kind.<<
Look at this:
By default it opens as a TIFF
By default it ads -Edit to the filename.
If Stack with original is selected it will store the edit next to your RAW file in the same folder
I know LR send a .tiff to PS but I have never noticed that LR/PS write to the hard drive directly with no warning which is what it is doing. Also what is the huge delay and the warnings which actually are not true? That is the point of my post and the problem. It is taking ages to process each photo (or group) which it has not done before my upgrade.
It may be worth checking your Windows 10 default applications.
System >> Default Apps
It could be that the setting for opening tiff files is defaulting to the Windows Photo Gallery or the Microsoft Photos app. Try changing the default for all tiff files to Photoshop CC 2015. If it is not listed, click the Find More Apps button.
Thanks for your suggestion. I have just tried that but has made no difference. I do not understand the massive delay and incorrect error messages. Isn't anyone from Adobe watching these forums?
It’s a bit puzzling. Does it work if both LR and PS are already open?
Try launching Creative Cloud and signing-out (click the settings – gear icon) and then sign-in again. Go to the Apps tab and wait for all the apps to refresh. When the buttons change to “Open” launch both applications and try again.
If nothing changes what happens if you chose from the LR menu:
Edit in >> Open as Smart Object in Photoshop
