Pack And Go is not working in SW 2009

Hello,
We installed sw 2009 (SP0) standalone few days back along with sw2008 which was already installed & then uninstalled sw2008 fromthe system. Pack n Go is not working in SW 2009 saying some"sldutils.dll" not found error. I tried to search this file on mysystem as well as on sw2009 DVD but failed.

Somebody please tell me how to fix this problem

Thanks
