”SQL BPA command line has encountered a problem and needs to close“的解决方法

There should exist on the server a directory named, C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\BPA\.

Create a new directory in this location named BPAClient.  You will end up with C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\BPA\BPAClient.

Copy the BPAClient.dll from the C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\BPA\Bin directory into this newly created BPAClient directory and try the installation again.

Note:  This is directly from an email I sent to support someone who was having this issue on their server and it worked for them.  They were running Windows XP.

如果是在使用Upgrade Advisor时出现该情况，解决方法为：

It works with the advisor too but it´s an other path.
C:\Program Files\Microsoft SQL Server 2005 Upgrade Advisor\BPA\
Then same steps as described
