After installing SQL Server 2008, you might get the following error message in SSIS when you try to open a package:
Failed to save package file “C:\TEMP\tmp18D.tmp” with error 0x8002802B “Element not found”

You should then get a message to let you know that it has been registered now. Once you’ve done this, try opening up SSIS again and hopefully you’ll be successful this time!
