This is reported working for other people, and i tested this specific feature on 2 other machines with no previous RR installs.
Did you remove files from this dir?
The script is fairly straight forward, in that it simply does a file copy from one dir to another
The only things i can think of that would break the script are,
1. you removed the files to copy from the ALT folder by mistake (maybe cut & past instead of copy?)
2. You have RR installed to a non default path.
Files that are copied are copied into this dir
C:\Program Files\Road Runner\SKINS\LSXVOID1.5
if you renamed the skin to something else, dont have RR installed into that dir then it wont work.
