Since this is a new install read the tutorials Acadia has provided links for before loading your hard drive with too many content.  In the freestuff section there is a pull down window to select your program application.  That way you only look at Poser stuff.  Also do not limit yourself to just Poser 7.  Poser 6 & 5 work just as well.  DAZ3D offers freebies every week and RuntimeDNA has a great selection of free materials and lights.  All you need to do is register and it's free.  I am not mistaken, you should be able to still pick up Free Michael 3 and Aiko 3 LE from DAZ.  I don't think Victoria 3 is available any more.

Great stuff!  Thanks for providing the links.

Here is another tutorial link which actually explains things a little better.  It is based on Poser 6 but the concept is basically the same.  Caution - Do not delete any folders created by Poser 7 in the runtime folder.  These are essential and is the point of reference for the program.  Also, some base models and character morph sets need to be in the core runtime to work properly.  However, your downloaded content can be individually removed either deleting the folders themselves or using DAZ uninstallers if provided.

If I understand your question, you are interested in creating external runtime folders other than the runtime folder provided by Poser 7.  Here is a link which should explain how to approach the organization:

Thank very much.  I was just at your site prior to checking the forum here and I noticed your post.  Again I want to thank you personally.  Can't wait to try these.

kuroyume0161 is correct, Dimension3D does have several Morph inj programs which work very well.  I was actually looking for one which would convert morphed character clothing into Inj/Rem pz2 files.  Found one in the Tool Collection series.

All versions of Victoria should work in Poser Pro.  Poser Pro is really a hyped up Poser 7.  There are situations where symmetry will not work correctly regardless of the figure.  It entirely depends on the pose.

If the problems began when you installed Face Gen Demo and 3DI runtime installer, I suggest uninstalling each separately and then run Poser.  It may just be that the programs are not agreeing with each other.

Depending on what you are looking for, there are various flavors of Injection pose programs around that may suit your need.  The DAZ programs (Yes, they have more than one) concentrate heavily on their millennium figures and work rather well.  I am not familiar with any script that would help create the files in Poser 7, but I can recommend Dimenion3D's tool collection which contain excellent inj/rem pose programs.  They are easy to use and yield excellent results.  I even used 1 program to create Inj/rem pose for an M3 bodysuit featured in my Superman avatar.  It worked better than I thought after searching everywhere for the right program.  The link is below:

I reloaded my version of Injection Magic to check your problem.  It is not my favorite program for creating Inj/Rem poses but it will do right now. 

Now, you loaded Aiko 3 into Poser and morphed her to your liking.  You generated a CR2 file by saving the morphed figure in the figure section of your library.  Since I-M was able to create an Inj pose pz2 I am assuming that Injection Magic was set up correctly.

When you go into Step 1 tab of Injection Magic, make sure that your input CR2 file is the morphed figure you created (if you see any reference to a Target CR2, that is your source file).  Under Parsing options, uncheck everything except 'Include Morphs' and 'Non-zero Morphs Only'.  Click the Parse File button on the right.  Let the program creat the CR2 Specifications.  Click Next.

Under Step 2 - Options, check everything under General Options on the right and 'Include Morphs' and 'Include Morph dial Settings' under that.  Everything else should be unchecked.  Click next.

Step 3 - Generate.  Click Generate.  If there are no errors a new window will open asking to save the Inj/Rem Pose into the Pose folder you have created for your new morphs.

If everything worked without a problem, go back into Poser, bring in an unmorphed Aiko 3 into the scene and then go to the Pose section to find your new Inj Pose Icon (button).  Make sure Aiko is selected and double click the Inj Pose button.  You should see Aiko morph with all your settings. 

It has been awhile since I played with this program, but I can tell you that it has worked for me just before writing this reply.  I can inject and remove my morphs without a problem. 

I am also including a link to a tutorial for Injection Magic.  It is a PDF so make sure you have adobe reader installed on your computer.

Let me know your progress.

Did you try clicking/selecting a different body part?

And I am assuming that you are using Injection Magic version 1.5?  Have you tried loading an un-morphed Aiko and applying the inj pose?

Agreed.  I would address the computer issue first since it might be on the verge of completely crashing.  Do you have an active antivirus running?  How old is the computer?  How old is the harddrive?  How large is the HD?  How much free space is available?  Have you run defragmentation software recently?  At this stage, if you run an antivirus deep scan, the system may reboot.

SnowSultan has put out seam guides for much of the DAZ figures.  It's a free download, just visit the site and go to the base figures webpage.  Somewhere on the bottom you'll find the download link.

Definitely a good fit.  Plain and simple but nice.
