The vmware virtualcenter server service terminated unexpectedly 7031

I was getting this error message when installing vCenter on SQL 2005. When I was setting up my DSN with the SQL Native client, I used used the SQL 2008 version because supposedly it was backwards compatible with earlier versions of SQL server. However, I fixed my problem by downloading and installing the SQL Native Client for SQL 2005. It can be downloaded here:

Another error you might get with the same issue is this when doing the install:

Setup has detected that the VirtualCenter Service is not running on this system. Please wait for the service to start and then try installing VMware Update Manager and/or VMware converter again.

Hope that might help someone.
