Question : Install Office Communicator 2007 fails on database

I am having the exact same problem as this person.

I can't uninstall SQL Express though as the server is an SBS 2008 server - I know I shouldn't have installed anything there, but I did.  Oh well.  Any other ideas on how I can install OCS on a SEPARATE box now?  I'm installing on a separate Windows 2003 server and I keep getting the error mentioned in the post linked above.

This is an urgent issue.

Answer : Install Office Communicator 2007 fails on database

I had to install on a completely different machine.  Nothing else would work.
