Just to expand a little on the technique to by-pass this problem:
Create a new folder anywhere on your hard disk away from your poser runtime ( so as not to damage your poser main rutime with a bungled installation).
Name it anything you like.
Inside this new folder create an empty text file, save it as anynameyoulike.txt
Rename the text file poser.exe
When windows asks you if you want to change the file extension, accept .
You may also need to create a subfolder called runtime.
And under the subfolder called runtime, create the sub-sub folder called libraries.
Tell the DAZ installed to install your Aiko4 or Vic4 or M4 into the new folder which conatins the fake poser.exe file
If Windows security complains, just tell it to shut up and just install.
If all goes well, the DAZ figure has been installed.
Run the initialisation as required by the installer.
VERY IMPORTANT: Rename the fake poser.exe into poser_fake.exe !!!
Launch Poser. You must then add this external runtime as one of the runtimes in your Poser library.
If you miss these last two steps and simply copied over the installation runtime into your main Poser folder, you’re so screwed, because it can, if you are not sharp with the Windows over-write warning, replace your Smith Micro Poser.exe file with your fake poser.exe file !!!
BE WARNED !!!
