can't double click on files or drag them into photoshop anymore - windows 10, PS 24.7.2

[bellevue scott]

I am no longer able to drag files into photoshop and have them open. I also can't drag files onto the PS icon in the toolbar and open them that way. If I double click on files then they open in PS, but when I try and drag them into PS in windows I get the little "no" circle with a bar through it indicicating that I can't drag that file into PS.

Any ideas? This is happening with tif files. I tried and saved a tif file as a PSD file and it still won't let me drag and drop it onto a PS window to open it that way.

You have mentioned in the title that double-clicking on a file does not work. That is an issue with file association.

Can you provide more details about the document that you want to drag into?

According to a forum post, you need to have administrative rights. You can find more details in this thread: Solved: Drag and drop of files on to Photoshop in the task... - Adobe Community - 12573255
