Remove the printer from Devices and Printers if it is there.
Now go to Programs and Features and remove the printer package from Programs and Features. If more than one, remove all.

Now go to Devices and Printers, and click once on one printer device. This opens the Print Server Management  tab. Go to Drivers, and remove the driver.

Close out, shut down, start up and try installing again.

The printer is not in any of those you mentioned. It refuses to install

Changed the Print Spooler to manual (in services.msc).
Run msconfig. Go to services tab and checked the box to hide all Microsoft Services and then disable ALL of the remaining services, saved and rebooted.
Not even in the driver tab?

Make sure Windows 7 is up to date including for sure ALL .NET Framework. People like to turn updates off
