SKU012.CAB missing

Once the detect and repair function is activated in Mircosoft Outlook, when ever I try to launch the excel spreadsheet system will prompt that the file SKU012.CAB is missing and require installation CD to solve the issue. When I click on cancel button then the excel wont be launched. I dont have the installation CD with me nor the license code. I have downloaded LISTOOL.EXE as instructed from some website but it keeps telling me for the installation CD which is not mentioned in the instructions. Can anyone help me please? Thanks
