You should have told that earlier when I asked to troubleshoot. All you said was that it didn't work. The errors are important though
Edit: Just thought that I should mention as well that when i got to start, run, and then services.msc it says that the installer is not started and will not let me start it. When I try to I get a 1067 error.
So basically, it's because the Windows Installer service won't start. Do you also have this on your new account?
Also, did you set the startup type for Windows Installer to automatic, clicked OK and rebooted? Did that work?
Also, go to services > Windows Installer > Login tab
click allow service to interact with desktop
then switch to automatic and restart the service.

Solution is posted there and it worked. Scroll down to see the solutions and follow them. It's with screenshots there.
Make sure you back up the registry first!
