I have copied all files from C:\Program Files (x86)\Embarcadero\Studio\15.0\Redist\styles\vcl to C:\Program Files (x86)\Embarcadero\RAD Studio\9.0\Redist\styles\vcl
In my XE2 IDE, I go to Projects->Options->Application->Appearance and the others styles from XE7 doesn't appear.
I also have copied C:\Users\Public\Documents\Embarcadero\Studio\15.0\Styles to C:\Users\Public\Documents\RAD Studio\9.0\Styles but it make all styles disappear.
How to make XE2 IDE read the new styles from another version of IDE?
Thanks.
