@Eku (Eku) posted a new topic, subject "Yaf(a)ray installation prob's (Vista) [SOLVED]". It read:

   OK, I've done my best to follow the instructions on the yafray site, and I've done the things mentioned in this thread as well…no luck. I get an error message, when I click on the yafray export in the Render drop-down menu, that it can't find the yafraycore.dll. Another odd thing: I don't see a yaf(a)ray “render” option in the Render Settings tab like the one shown by Alvaro, other than the old yafray selections. All of the scripts seem to be in place in the .blender/scripts folder, so I'm confused big time. Yet another Odd thing: when I went to install yaf(a)ray, it defaulted to putting the scripts in a folder called something like “roaming/appdata;” I redirected to the blender folder instead. This is a Vista thing. Well, it didn't work, so then I uninstalled everything (Blender included) and the reinstalled. This time _Blender_ wanted to put things in the roaming/appdata folder…so I let it, and let yaf do the same…still doesn't work. I'm sure I have all the right tools…Python 2.5.1, the qtsetup, the proper MS redistro (got it right from the yaf site). I think it has to do with that “roaming” thing, but I've done it both ways, no go. UAC is off. I'd copy the info from the console for ya, but I can't quite remember how to do that…I know I've done it before. Gist: importyafray seems to cause problems, and then it says the DLL load failed. Help?

After which, @Alvaro (Alvaro) added

    It is not a problem with the registry, because the Blender console would tell you so.
    
    I don't know for sure what could be wrong. Anyway you can try this: in the fith step of the Blender installation process, you are given tree options about where to install data files: app data directory, installation directory and home variable.
    
    Use the second option so Blender will create the scripts folder in the Blender executable folder.
    
    When you install yafaray again, the installer should point you to the scripts folder in the Blender executable folder to install yafaray scripts there too.
    
    Remember that the MS redistro needed is 2005 SP1 and python should be 2.5.2, no one else will work.
    
    Also I suppose you have installed yafray binaries in **c:\programs files\yafaray**

Then @Eku (Eku) said

    Thanks for the reply…I'm at work now, installing yaf on my work 'puter, which is XP. We'll see how that goes, but the one thing that looks obviously out of sync for me: python 2.5.1 vs 2.5.2. (I had assumed any 2.5 would work.) I'll try that when I get home, along with the reinstallation of all the packages. I assume that I only need to install the qtsetup once, right? (I won't uninstall.)
    
    EDIT: update, I got it running fine on my XP work computer. I'm thinking its the python. I'll post again once I'm home, either way.
    
    EDIT 2: yep, it was the python - after I installed 2.5. **2** , it works great on my home computer now. Thanks, Alvaro!
