redistributable not being installed because it was installed before the reboot

I have added a prc to install c++ vs 2013 redistributable to an Installshield project I have inherited. When I run the setup.exe and get a debuglog I see the following:

Can someone explain why the redistributables were not installed and what I can do to get them installed.

Thanks
