If you’re upgrading SalesLogix for Remote users, and doing that on SQL Server Express Edition 2005, and having to reinstall SSEE because they’ve lost the sa password (etc.), guess what?
Before you do that, if Microsoft MSXML 6.0 SP2 exists on the system (in Control Panel, Add/Remove Programs), you have to uninstall that, or the SSEE installation will fail, with an error message (displayed via a hyperlink to the setup log file, not via a dialog box) that DOES NOT give you much help in figuring out what actually went wrong.
And you can’t uninstall MSXML 6.0 SP2 from Control Panel (Add/Remove Programs), either. Instead, you have to download the Windows Installer CleanUp utility, and run that separately.
