I just got Fallout NV and I'm trying to install Wrye Flash so I can manage my mods. I have been using Wrye Bash for Oblivion for 2+ years and I love it, which is why I've gots to get me some Wrye Flash. I know I have Python installed successfully because, well, I can run Wrye Bash. But for some reason, no matter what I try with Wrye Flash, it won't start. I have Wrye Flash version 12 from TESnexus. I merged the Data folder with my NV Data folder and put the Mopy folder in my NV directory, as per standard Wrye B/Flash installation procedure, but for some freakin' reason, when I try to launch Wrye Flash, nothing happens. I can still use Wrye Bash just fine for Oblivion though.

I"d greatly appreciate any help with this problem.

you have to download the wrye python thingy from tesnexus. its very picky about which version you have installed because i had 24 and 25 installed but the newer version use 271. i had the same issue when i recently updated my wryeflash.
