If you have Word 2003 installed, you might have came across this error. Sometimes it is just annoying to have it keep popping up, but sometimes the Word documents won’t even open because if it. The easier way to get rid of it is to insert the Office 2003 CD and have Windows install the needed files from it. What happens if you don’t have it though? Well, the process is quite simple and does not require a system restart.Go to Start-> and type REGEDIT. Press enter and browse to:HKEY_LOCAL_MACHINE -> Software -> Microsoft -> Office -> 11.0 -> DeliveryUnder delivery you should see the following key 90000409-6000-11D3-8CFE-0150048383C9Click on it and on the right side of the screen right click on the CDCache key and select Modify (in bold).Type 0 as the new value and click enter. This should now take care of your error.Cheers!
