I receive the error: The file could not be edited because Adobe Photoshop CS6 could not be launched. After the error, LR creates a tif file and that does open up in PS. I have uninstalled and reinstalled PS and LR but the error comes back. I am running LR 5.7 and PS CS6 both with ACR 8.7. I have seen numerous posts on this issue but I have not found any resolution.
