OK - but that doesn’t tell me whether you have been granted local administrator rights on your own computer.
If you can log in as administrator and run the install again, that would be advisable. Otherwise I would recommend contacting the person in your company who is responsible for administrating your company domain to check what rights you have locally when you are logged in as a user.
I think this is likely to be the cause of the problem. You could also try a reboot of your computer to see if any component registration tasks have been deferred by the installer.
