Plug-in Compatibility
In general:
- 3rd Party plug-ins that are compatible in Photoshop CS5 should be compatible in Photoshop CS6

- Photoshop CS5 Optional Plug-Ins (Mac/Win)
- TWAIN plug-in | Photoshop CS4, CS5

Installing plug-ins in Photoshop CS6
- Do:

- Use the manufacturer's plug-in installer to install their plug-ins
- Don't:
- Do not point Photoshop CS6's "Additional Plug-ins" preference (Preferences>Plug-Ins...) at a previous version of Photoshop's 'Plug-Ins' folder.
- Do not manually drag plug-ins from a previous version of Photoshop's plug-ins folder to Photoshop CS6's 'Plug-Ins' folder
