Did U extracted normal.res from aero.msstyles
or just opened aero.msstyles in hex editor?
If normal is not extracted the address is different.
Try in hex editor click on find string and enter FC FC FC and see what happens
Addresses for x64 in picture I get 1,2,3,4,5 when searching for strings fcfcfc E188,23038,23060,23088,2C1E0.
But if U put aero and try to search for strings there are a lot of fcfcfc.
If show only 5 on extracted normal.res U good to goo just compare the addresses for x64.
