Symptom: Office install wizard searches for SKU011.CAB, but you cannot find it on neither your local installation nor your installation source.
Solution: Open your registry and navigate to HKEY_LOCAL_MACHINE > Software > Microsoft > Office > 11.0 > Delivery > 90000409-6000-11D3-8CFE-0150048383C9. Change the value of CDCache to “0” (zero).
Any other value of CDCache (e.g. 2) indicates that the current installation has been created using a installation cd using packed installation media, which includes the desired cab files. However, if you try to copy installation media from a network installation, this fails. After changing the value, try to restart your installation, it should succeed.
