If you have installed a new version of Photoshop, you may find that the command to "Edit Menu in Photoshop" no longer works.
The fix for this is simple. Just re-associate the .PSD extension with the new version of Photoshop.
You can do this in a couple of ways (all versions of Windows).
1 - Find a folder with a .PSD file in it.
Right-click the file, and choose the "Open With" dialogue.
Select the new installation of PhotoShop, and make sure that the check-box for "Always use this programme" is ticked.
Click on Open, and from now on all PSD files should be associated with the new installation. Some systems might require a restart to lock the association in.
2 - Go to Start/Settings/Control Panel/Folder Options.
Click on the tab marked "File Types".
Scroll down to the PSD type, and set the "open" command to the new installation of Photoshop.
That will do it.
