Now that SP2 for SQL 2008 has been released it is time to update our SQL 2008 slip-streamed installation files. The slipstream process is the same, but I did run into one bug once the process was completed. There appears to be a bug that when you have a slip-streamed version of SQL 2008, the installation cannot be run from a network drive when .NET 4 has been installed. The following error may be received when attempting to launch setup.exe.
