VxWorks怎样安装啊?

  我安装WINDRIVER.TORNADO.V2.2.AND.VXWORKS.V5.5.FOR.PENTIUM-RORiSO是按照
Installation :
  
1. Install Tornado, use this serial when asked:
   cAQ8i-qP2I&-g$vT6-3&gjw-bEk9
  
2. Copy the license.dat to c:\\flexlm.
  
3. Set the following environment variable:
   LM_LICENSE_FILE = c:\\flexlm\\license.dat

可是license总是找不到. 请问各位大侠, 我应该怎样做啊?

谢谢
