I did. I have a seperate folder called "Editor", with 'data' 'levels' 'save' and 'sound' folders (which I created), also copied the 'LDATA' folder, Editor.exe (from this site), 'keeperfx.cfg' 'Mss32.dll' 'SMACKW32.dll' 'WSnd7R.dll in the main folder, then, in 'DATA', I left all the files in there and added "GUIEDIT.DAT" "GUIEDIT.TAB" and extracted the 'edittext.rar' (from this site) into the 'DATA' folder, I didn't delete any files from step 7 or step 9, I extracted the empty levels file in "levels" (I have DDISK1.LIF, DDISKMP.LOF, DKLEVELS.LOF and an empty 'LEVELS.txt' in the 'levels' folder) and I right-clicked Editor.exe and I have the following checked "Run this program in compatiblity mode for 'windows 98/ME'", with settings 'run in 256 colors' 'run in 640x480 screen resolution ' "disable visual themes' 'disable desktop composition' and 'disable display scaling on high DPI settings', and I do NOT have 'run as administrator' checked (I have tried both administrator and non-administrator settings) (all this I am doing in the Editor folder, not Keeper FX folder)
