Error occurred while validating servicing step Add Running User to the TFSADMINROLE for component Install during Install: Unable to deserialize servicing step data to type Microsoft.TeamFoundation.Server.Servicing.TFCollection.AddSqlRoleMemberStepData.

This is a known problem registered in Microsoft Connect:

When I use domain\user and the domain has '&' in it, this error occurs. I don't know what to do anymore.

For more information, see the configuration log.

So my guess is that somewhere in your domain, group, service or user name used during installation and configuration of TFS, there is a symbol included that cannot be deserialized correctly. Thinking about symbols like < > & %.
