Hello and thanks for all the work put into this as its always a game changer.
I am still getting the same fatal error after using the SSE launcher and verifying through steam and have followed your steps and suggestions. I made a post here on step in MO support at
https://forum.step-project.com/topic/13130-issue-with-apps-launched-from-within-mo2/
I tried to take things a step further by experimienting with adding my DynDOLOD directory contents in through MO overwrite to see what would happen. After activing the files in MO I no longer get the fatal error. MO reports process completion but nothing happens TexGen does not pop up. However I noticed the six optional ESP's available now Overwrite.esl, esm, esp, RNAM.esl, RNAM.esm, RNAM.esp.
Is there another guide to follow explaining if playing with these files will help? Otherwise I suppose I will have to install the related files manually into my vanilla directory in order to get the tools to work. Then remove and paste into Overwrite. Or I could wait for updates and fixes. I suppose I should mention I am aware Vortex is on the way so MO support is what it is right now.
Thanks again
