How to set pdf creator 2.5 default output to tiff

Can someone tell me the Win 7 registry setting (or file to be changed) on version 2.5 to have any new user's output to tiff file as a default?

This is for the the terminal server version.

Thank you in advanced!!

Just copying my email here, so everyone is able to read my proposed solution :

Please find the guide to create default settings on PDFCreator Terminal Server here: http://docs.pdfforge.org/pdfcreator/2.5/en/pdfcreator/pdfcreator-settings/predefine-settings/#create-defaults-with-pdfcreator
If the users did use PDFCreator in the past, you will need to delete their settings from the registry, so they can get the new default settings.

You can delete the following keys from your users registry, if you wish to delete all settings: Computer\HKEY_CURRENT_USER\Software\pdfforge\PDFCreator\Settings

If you wish to manually change the output format in the registry, you can change the value of the OutputFormat key in Computer\HKEY_CURRENT_USER\Software\pdfforge\PDFCreator\Settings\ConversionProfiles\0 to Tif
Please note that you will need to apply these changes to all profiles that should use Tif.
