The installation of iCS will finish, and then attempt to kick off the configuration wizard. The first step of the configuration is to create a printer, and in this case the Windows Print Spooler service was disabled
In Windows Services, set Print Spooler to startup "Automatic"
Start the Print Spooler service
Rerun the configuration wizard (Start-Programs -Bentley-ProjectWise V8i (SELECTseries 4)-Bentley i-model Composition Server for PDF-Bentley i-model Composition Server Configuration)
