Nope, I'm using framework 2.0 (the link from the download page), and actually stumbled across my own answer with a bit more looking. In my endless tinkering, I'd enabled a security option to only use "fips compliant algorithms", which nlite apparently is not. After I turned off that option, nlite ran just fine. Though now it refuses to properly burn a cd (the disc keeps failing verification). However, if I simply create an image, and use a program like clonecd to burn that image, it runs okay. (except for some missing driver files, but that's a whole 'nother issue).
