Use this document to identify problematic plug-ins in Adobe Photoshop CS5 or CS4. This document also provides instructions for restoring the default set of Photoshop CS5 or CS4 plug-ins.
Plug-ins are software modules that extend the capabilities of Photoshop. For example, some plug-ins enable you to apply special effects to images, while others enable you to open or save various image file formats.
When you installed Photoshop, many plug-ins were installed automatically. If you subsequently installed any third-party plug-ins -- plug-ins from a publisher other than Adobe -- and if you are troubleshooting unexpected behavior in Photoshop, then a third-party plug-in may be causing the problem.
A plug-in can cause a problem in Photoshop for any of these reasons:
- The plug-in was designed for a different version of Photoshop and is not compatible with Photoshop CS5 or CS4.
- The plug-in was installed incompletely or incorrectly.
- More than one version of the same plug-in is installed.
- A plug-in file has become damaged.
Some of the steps in this document have different instructions for the 32-bit and 64-bit editions of your Windows operating system. If you do not know which edition of Windows you are using, see "Determine whether your computer is running a 32-bit or a 64-bit edition of Windows" (TechNote kb407673).
Note: To troubleshoot issues with the Adobe Camera Raw plug-in, see "Unable to open camera raw file in Photoshop or Photoshop Elements" (TechNote kb407110).
