I am sorry to hear that you have experienced issues with evaluating the product. We are currently working on getting a build out that will run against the RTM version of Silverlight 4, and will be releasing it as soon as possible.
In regards to the SQL Server Express requirement, supporting existing SQL 2008 instances is definitely a feature we are looking to provide, as we understand many customers do not want to install Express instances, although I can not specify a timeline around when this will appear.
As for the installation errors, we would be happy to work through those issues with you on the machines in question. Based on your screenshot and your comments, I am guessing that a lack of SQL Express was indeed the issue on those machines. Do you know for sure if those machines had SQL 2008 Express installed on them? If not, does installing SQL 2008 Express allow TeamPulse to successfully install?
