Having challenges installing standalone SQL 2008 components?
If you are, then Herleson Pontes has your answer.
Windows Installer 4.5 is now out, but according to Herleson it is not available via Windows/Microsoft Updates, so head over to his blog for the link or hit it directly at http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=5a58b56f-60b6-4412-95b9-54d056d6f9f4.
Thanks Herleson for picking up on this!
