As far as I can tell, there is no way to update PDF Creator user settings, other than on installation.
E.G. If you set the REGFile=settings.reg, you can apply PDF Creator settings to HKEY_USER\\.DEFAULT\\, these get copied to each user when they first run PDF Creator. This is good.
However if we then want to update the user settings, it is impossible. The user already has PDF Creator settings in the HKEY_CURRENT_USER section, and these are not overridden by HKEY_USER\\.DEFAULT\\. Furthermore, even if you uninstall PDFCreator, it still doesnt remove the HKEY_CURRENT_USER registry key from users!!! They will still get the same settings even if you re-install with new settings!
So how on earth do we update user settings, without going to each users computer and removing there registry keys under HKEY_CURRENT_USER?
Thanks for your help!
