"Please open a document to use this feature"

[Amos Keppler]

when I try to use adjustments. But I have several documents open. I can't use adjustment, which is certainly an inconvenience. I haven't found nay other functions not working yet.

 I have a fiarly new windows machine with 16GB ram and SSD disks. It doesn't have any graphic card. PS 25.1

You mean you do not have dediacated Graphics Card? You can not do anything visible on screen without GPU. You have probably integrated GPU.

What happens when you try to use Adjustments? Can you describe steps and outcome/versus expectations. Some screenshot will be worth many words.
