UnRAR the archive to your “My Documents” directory, overwriting any existing files.
Always unRAR with full paths!
Only Profiles # 9999 and # 9998 will be overwritten, hope you did not make that many profiles already.

a) Run the game once to force the game to write files to “My Documents”.
b) Search your system for the directory “RCT3”.
