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”
This just means that you’ll need to register the MSXML dll manually. To do this, open a command prompt and enter the following command:
regsvr32 %windir%\system32\msxml6.dll
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!
