I've reinstalled Poser at "c:poser" instead of "c:program files..." etc.

However, the DAZ installers still prompt for the old path whenever I install an item. I have a lot of items to set up, so I'd like to change the entry manually. It's not in the registry; I'm using Vista Home Premium, so I'm guessing it'll be in the local settings, but I haven't found it yet.

Could someone let me know?

You should be able to override the old path depending how old the installers are.  Some DAZ files will actively search your hard drive for Poser.exe file and allow you the option to install in multiple Poser programs.  You could actually cancel this and install it manually.  Other individualy like to uninstall in a temporary folder and then manually transfer the content to either the primary Poser runtime or external runtimes.  Now I don't believe that you can redirect your installations using any local settings in Vista (Sorry, not very familiar with the OS yet).  I believe the installs are hard wired in the files themselves. 

Found it; the installers write to DZINSTALL.INI, located in Program FilesCommon FilesDAZ.

Thanks, Ive been looking for that solution.

Sometimes the installers from Daz get locked on a certain path and one has to enter prefered new path manually for every file.

Access to this file will fix that.
