So you mean instead of running LJTD v.6.3 on a 8.1 Windows you are now running it on a 7.0 Windows SP3 and the Framework error is gone?
Or do you now mean the upcomging LJTD 7 Version? Sorry but I’m a bit confused now. Try to always say what you tested (LJTD Version) and where (which system(Framework). I don’t think that compability will help there. I think the problem is somewhere else. A TeamViewer session could help very much if that would be possible. Add me on skype “kwoxer”.
