When you choose a Photoshop script in Bridge or Photoshop, such as Merge to HDR Pro or Image Processor, an error appears. For example:
Rename the hard disk to a nonconflicting name. For example, make sure that the hard drive isn't named "Applications," "System," "Library," or "Users."
Rename network drive to a nonconflicting name, if possible. For example, make sure that you don't have drives named "Applications," "System," "Library," or "Users." If not possible, disconnect the network drive while using Photoshop.
If you have duplicate hard disk or network drive names, then rename some to eliminate the duplicates. Make sure that all of your volume names—hard disk and network—are unique.
