I know this might be kind of late for some of you but I just had to perform an upgrade to our SQL server as our last vendor now supports SQL 2005.
But I ended up with a problem. When upgrading I got an error (-1). What the hell it that? It was totally non-descript. When clicking on help it stated that I was not using a strong password!?! I was using Windows authentication so i decided to use the “sa” login and got the same error. Then proceeded to look for the fix.
I found it on eggheadcafe.com
Go to c:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\BPA\bin
Go up one level to c:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\BPA
Paste BPAClient.dll there and then try the install!
Then it works.
Thanks to chaitu for this fix.
