I am having the same problem with Robot Structural Analysis Professional 2016 Service Pack 4 installation.
"Installation Error: A problem prevented the Update Release from being installed. Contact your system administrator. Error Code: 1625".
(it is a Service Pack, not Update Release, but it doesn't matter).
User doesn't have Admin rights so I tried right click and "Run As Administrator" but no luck.
Maybe the problem was that I did the whole thing via TeamViewer?
Error 1625 usually means insufficent rights. Please log onto the PC using ADMIN rights instead of running as admin.

Thank you Mark!
I understand, and I thought so.
As I am concerned, it is not the software (Robot) issue so I will ask System Admin to solve this.
