I'm sorry you ran into this issue. ProSeries is attempting to update a Microsoft Library it depends on (Visual C++ runtime). Allegedly that 1618 indicates another installation is in progress (other than ProSeries... we use a different installation technology that shouldn't interfere with Microsoft).
Could you restart your machine, download and run the Visual C++ Installer directly?
If that works, then try the ProSeries installer.
If that doesn't work, reply here and we'll try something else.
Again, sorry you've run into this problem.
