Just a quick post as a reminder, I was recently at a client where projects failed to save to Project Server. The key error shown in Project Professional and in the Project Server queue was:
error id =”12005”
error= System.Data.SqlClient.SqlException: Execution of user code in the .Net Framework is disabled. Enable “clr enabled” configuration option
The error states the exact issue, CLR needed to be enabled on the SQL Server. The steps to enable CLR are documented here:
