Then you're doing it wrong. It's obviously either the uncorrect folders or the uncorrect files. Check again all steps: the set have to be decrapped before being installed as you like (launcher or packages), then put the "KT_StoreFix_DecrapFixes" and the "ccmerged" file in your Override folder, delete the compositor cache.
I put ccmerged file in the DCBackup folder, and KT fix in the mods folder, but it isn't working..
Sorry for butting in. I put "KT_StoreFix_DecrapFixes" in the "mods" folder (where both the 'overrides' and 'packages' folders are) since I use sims3packs instead of packages. I think you should only put that file in the "overrides" folder if you're using packages. Not sure if 100% correct, but this seemed to fix the issue for me.
*Oh and I have two copies of the updated ccmerged; one in the "overrides" folder, and one in the "DCBackup" folder.
