With Sketch Up 2017, we have completely reworked our graphics pipeline - i.e., the way we display Sketch Up models.
This was a massive change that will allow us to innovate far beyond what we have been able to do in the past.
In essence, Exchange 2016 and Exchange 2013 follow the CU model (getting security patches separately), while Exchange 2010 and Exchange 2007 follow the RU model (with security patches included).
Microsoft uses the term, "customer rollup update" (RU), interchangeably with "update rollup" (UR), which presumably explains the strange RU abbreviation use.
Most likely Exchange 2003 wasn’t decomm-ed properly (if you are no longer using Exchange 2003).
Solution: Error ONE: Ignore the error “[2/16/2015 AM]  [ERROR] The operation could not be performed because object ‘exchserver01’ could not be found on domain controller ‘adserver01.domain.com’.” Just proceed with starting the Windows Firewall service and rerun the update of Service Pack. You will not be able to delete the Recipient Update Service (Enterprise Configuration) by using Exchange 2003 or Exchange 2000 System Manager.
If you see this error dialog, try upgrading your graphics card driver - upgrading your driver is a good first troubleshooting step and often solves the error.
We explore the attributes of equal weighting and explore FTSE Russell’s enhanced methodology, which has an added benefit over simple constituent equal weighting by enhancing sector diversification.
You verify from the Domain Controller adserver01.that the Exchange server object is there.
You also verify that the Exchange Server is able to communicate with the adserver01.Error TWO: “.” You will need to remove the RUS manually.
This new graphics pipeline has stricter hardware and software requirements than in previous versions of Sketch Up.
To run Sketch Up, you will need: If your machine does not meet these requirements, you will see an error dialog when launching Sketch Up, Lay Out, Style Builder, and Viewer that lets you know which requirement you did not meet and which will prevent you from running Sketch Up until you fix the error.
