You have to know that renaming that folder will delete all customization. Some can be copied from the renamed folder.
If you are on Win7 it is labeled Captivate 6 in this path: \users\<your username>\AppData\Local\Adobe
If you didn't customize a lot, you can also use run the CleanPreferences file that you find in the folder Utils under the Captivate installation folder.

BTW: tested like Rod, even for old files I can tick that option
