Re-creating the Flash Professional preferences file sometimes resolves unexpected issues or unusual performance, such as a system freeze. 

Re-create the preferences file to restore the following items to the default settings:

  • All preferences
  • All workspace settings
  • All panel positions
  • All behaviors
  • All Project settings
  • All cached custom classes saved to the Flash programs folder 'First Run' folder
  • All custom commands such as Motion XML in the commands menu

Save custom settings (optional)

To save custom commands and other settings, create a copy of this folder:

CS6

  • Windows: C:/Documents and Settings/<user name>/Local Settings/Application Data/Adobe/Flash CS6/<language>/
  • Windows Vista & Windows 7: C:/Users/<user name>/AppData/Local/Adobe/Flash CS6\<language>\
  • Mac OS X: /User/<user name>/Library/Application Support/Adobe/Flash CS5.5/<language>/

CS5.5

  • Windows: C:/Documents and Settings/<user name>/Local Settings/Application Data/Adobe/Flash CS5.5/<language>/
  • Windows Vista & Windows 7: C:/Users/<user name>/AppData/Local/Adobe/Flash CS5.5/<language>/
  • Mac OS X: /User/<user name>/Library/Application Support/Adobe/Flash CS5.5/<language>/

CS5

  • Windows: C:/Documents and Settings/<user name>/Local Settings/Application Data/Adobe/Flash CS5/<language>/
  • Windows Vista & Windows 7: C:/Users/<user name>/AppData/Local/Adobe/Flash CS5/<language>/
  • Mac OS X: /User/<user name>/Library/Application Support/Adobe/Flash CS5/<language>/

CS4

  • Windows: C:\Documents and Settings\<user name>\Local Settings\Application Data\Adobe\Flash CS4\<language>\
  • Windows Vista & Windows 7: C:\Users\<user name>\AppData\Local\Adobe\Flash CS4\<language>\
  • Mac OS X: /User/<user name>/Library/Application Support/Adobe/Flash CS4/<language>/

To restore custom settings, copy the commands folder (and Projects or other needed custom settings) back into the original location and restart Flash Professional.

Re-create the preferences file

Note: You can skip the following steps if you do not want to save your old preferences. You can start the application while holding Ctrl+Alt+Shift to delete and reset the preferences to the default.

To delete the preferences on Windows, delete the following registry entries.

Warning: The following solution involves the Windows System Registry. Editing or manipulating the registry incorrectly can result in serious system damage which sometimes requires reinstallation of the operating system. If you are not comfortable editing the registry, then take your system to a professional. If you choose to proceed, make sure that you create a complete system backup and a Windows System Restore Point before proceeding. Adobe Systems cannot be held responsible for damage resulting from this information.
