Solved: Cannot Install SimCity

I installed SIM CITY 3000 on my computer some time ago and later uninstalled it. I tried to reinstall it recently but was unable to. When autorun from the CD the following appears in a dialogue box:

When I double click on "Setup.exe" on the SIM CITY CD the Installation Program starts and I click next, the following is displayed in a dialogue box:

This is incorrect, Simcity 3000 is not already installed on my computer.
I click "Yes", the following is displayed in a new dialogue box:

I click "Ok" and setup ends.I have far more than 33444 bytes of free hard disk and I ran the disk defragmentor to clear even more. When I try again I keep getting the same result.
I access the "Add/Remove Programs" in "Control Panel" and see that Simcity 3000 is listed there (along with mountains of other applications I have long since deleted). I highlight it and select the "Add/Remove" button. Uninstall shield runs. Afterward SimCity 3000 is still in the Add/Remove Programs List.
Could you suggest how I might fix this?

 

Have you deleted the Simcity folder in the hard disk. Usually the folder will not automatically being deteted it when you uninstall your game.

 

I have deleted the SimCity folder on the hard disk. But the problem persists.

 

You may need to run a registry cleaner.......

 

You mean like RegCure or Registry Mechanic that are advertised in this forum above? I have tried those. They will not do it unless I register with them. Can you suggest anouther registry cleaner ACA529?
