Photoshop CC 2015: Can't double-click to open .PSD files if Photoshop has been opened from Lightroom on Windows

Here's a weird bug that I discovered:

If I open Photoshop by editing a PSD file from Lightroom (hit CTRL-E when PSD file is selected, choose "Edit Original" from the options), that file will open correctly. Then, if I try to double-click a PSD file in Windows Explorer while Photoshop is still running, the file will not open. I am also not able to drag a PSD file from Windows Explorer into Photoshop to place or open it.

However, if I close Photoshop completely and then double-click the PSD file from Windows Explorer, Photoshop works as expected. It opens the file. In this situation, I am also able to drag files from Explorer to place or open them.

Can anyone else duplicate this issue?

Did this start after the 2015.1 update? Or an issue you've been having for some time?

This started happening only after upgrading from Windows 7 to Windows 10. The problem was present in the previous version of CC 2015 but I waited to see if this update would fix it. Since the update didn't resolve the problem, I decided to report it here.

No, I can't duplicate this issue on my Windows 10 system. Everything works as expected.

Thanks for testing. Did you upgrade from another version of Windows or start with a fresh install of Windows 10?

I initially upgraded from Win7, but there were a few too many niggles with the result (non-Lightroom), so I then did a clean install of Win10. Because I rarely open Tiff/PSD files directly into PS from the Windows file system, I can't say if there might have been your issue after the first upgrade installation of Win10.

I tried uninstalling both LR and PS and reinstalling them. I'm still experiencing this issue. Not sure what to do about it.

I solved the problem! It turns out I had Lightroom set up to "Run as Administrator" because I was trying to solve some other issue with it. Apps "Run as Administrator" are not allowed to open files from Explorer. As soon as I disabled that option, I can open .PSD files again.

Technically, I think it's that apps not running as administrator (e.g. File Explorer) cannot request apps running as administrator (e.g. Photoshop) to open files. If File Explorer were running as administrator, it could ask Photoshop to open files.

This has struck others, typically when they try to drag and drop into LR. Always a very confusing thing to troubleshoot, since it's not at all visible which apps are running as administrator, and that might have been configured a long time ago and forgotten.

Glad you got this figured out!

Yes, you're right on all counts. I set the "run as administrator" on LR ages ago to try to fix the sluggish performance after I upgraded to Windows 10. Then came the LR update that fixed that problem and I totally forgot that LR was set to run as administrator. It would be great if Windows had some kind of indication in the title bar of the window that the app was running as administrator. I'm sure that would be both a great security feature and troubleshooting tool.
