Trouble reinstalling alcohol for Windows 7

I was working with 1.9.8.7612 (latest) on my Win 7. worked fine. Had to uninstall. "Uninst" was giving me error messages. deleted manually. Now installing again and everytime i get to installation process (SPTD screen), its asking me to restart the computer. after restart program starts again, and when STPD installation screen goes on I get the same message.... to restart my computer, and so on. What do I do? cant even install Daemon tools, gives me the same message.

For that you need to run "regedit on your pc. Then you need to find out "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{E9F81423-211E-46B6-9AE0-38568BC5CF6F}" on your machine and then delete it. After that again find out "HKEY_CLASSES_ROOT\Installer\Products\32418F9EE1126B64A90E8365B85CFCF6", and you need to again delete it. Then try to reinstall alcohol on your Windows 7.
