Пишу так:
Reg:=TRegistry.Create;
Reg.RootKey:=HKEY_CURRENT_USER;
Reg.SaveKey("\Software","C:\Soft.reg")
Создаётся пустой файл.

Читаем внимательно хелп
On FAT file systems FileName cannot include an extension.

Ну в дополнение еще куча проблем
1. это не reg файл
2. нельзя использовать HKEY_CURRENT_USER
