Windows 7: Windows Installer Error 1719, Service Missing

I recently (as in yesterday) cloned my Windows partition over from a HDD to a SSD. The clone was successful, and supposedly without errors. Everything seemed fine until I tried installing Steam again, to start redownloading all of my games.

In short, I got the following:
"Error 1719. The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance."

In getting this, I obviously did what any normal person would do, and used google and the search function. There, I found some of the solutions, such as unregistering and re-registering the msiserver/msiexec registry. I also tried some other things with the registry to try to fix it.

And then I got to the fix where it said to access the services.msc and modify the service to start automatically, and etc. And of course, I went to try out this solution... To find that Windows Installer was not even under its services.

I'm just curious as to if there is anything I can do, without having to do a clean install.

Thanks.



EDIT/UPDATE #1: When Super Malwarebytes updated itself, and installed the newest version, the installation went on without a problem...
