We had multiple quick power interruptions right before the storms hit North Texas Wednesday night.  Since then,  I can't get Poser 7 to work.  I am working on a PC with Windows XP home. 

I tried doing the partial install and the total install over the files and that didn't work.  It opens with Simon so it is reading the geometry and texture files.  It won't let me save Simon to the figures file either. 

I'm ready to do an uninstall and reinstall.  However, all my Geometry, Texture, Python and Morph files (some are unique some are copies from the external runtimes which contain all the library files).  What files do I need to protect by copying to a different drive before uninstalling?  What files do I definitely not want to keep in case they are causing the problem? 

All help is greatly appreciated!  I've been poser-less for several days and I'm really getting frustrated--particularly since the weekend is my main time to play in Poser.

Personally I would Back up the whole main runtime, but only restore the "Geometries", "libraries", "Python", and "textures", at least for a start. You should also back up the "ReadMe's" folder from your main Poser folder, and any folders with a similar name, eg "Nerd 3D Readme". Also the "Downloads" folder if you use that. And if you placed any other runtimes under the main poser folder back them up as well.

All the files needed to make figures and props work should be under the...

Geometries
libraries
textures

...folders. But of course you will also want the keep readme files and Python scripts. The other stuff in the runtime folder is mostly to do with settings or preferences, like the "preferredState.pz3", "Poser.ini", UI and Camera Dots, render settings, and such, or is stuff that the reinstall will replace. Your pz3 (scene) files will be where ever you saved them to.

If you are going to do a full install, save your full runtime  somewhere else
dont copy back the full python library , copy over selected scripts, the python modules themselves will be relaoded in the full install. 

First try finding documents and settingsuserapplication dataposer 7   where user is your login name on your pc . delete all the files there . Then try starting poser again .

runtime/geometries runtime/textures  runtime/libraries should be safe to reinstall

what les said but I disagree on the python folder :)

Poser 7 was installed in an external drive.  I deleted all the files other than geometries, textures and libraries.   I finally got it to work after deleting over 400 poser related files off my hard drive (some of which dated back to Poser 4, 5, and 6) and that did the trick.  I originally forgot to run all three updates and got some weird errors but that is no longer a problem.  Just and FYI, update 3 has an option at the end of the install to delete all the pref files in case you are moving Poser 7 to a new drive.  I wish I had started with that.  Thanks to everyone for your help.
