Like the above. I also had this problem but adding the --single-process flag solved the problem. Installed both MO 1.2.18 and LOOT v0.7.0 Beta 4 outside Program Files (x86), and also have UAC disabled in Win7.
The Main File for that mod is 2048x2048, that has the 3 candle textures in it (78 textures total). The 1024x1024 optional file (STEP recommended) does not have those 3 candle textures (75 textures total)
Don't know if this is the correct place to ask... but this mod contain files not included in the STEP Extended Patch, its esp also has an entry that hasn't been copied to the STEP patch... Should I still not install it?
I get the following warning after I completed STEP 2.M.: Everything is installed in the order they are on the https://wiki.step-project.com/STEP:Guide page. Should I move anything in my install order?
