Whilst we were testing the setup, we knocked up a Win2k3 server, and the install went smoothly.
However, building the server for real for a customer, we could only acquire a 2k8 R2 server licence. AD's configured, MAPI-CDO's installed, Outlook (2003 since 2007 refuses to) is installed and working. But the Scalix connector doesn't play.
The installer launches, fires up the usual security dialogue box, seems to get a fair way through - the progress bar whips across to about 2/3, but with no detail of the actual progress above the then the installer fails. "The wizard was interrupted... Your system has not been modified". There's one other oddity - it's not finding any updates for Outlook.
Only message in the event log is...
EventID 1033, source MSIInstaller - "Installation success or error status: 1603"
Any thoughts?
