"Interactive Services Detection" message pop up every 5 minutes

When i tried to install Program that was actually "Windows Installer", it was showing me the message "Windows Installer couldn't start" so I have followed Ztruker's advice. I Changed CMD directory to "WINDOWS" using this code: "CD C:\Windows" and then typed: "dir msiexec.exe /s". After 5 minutes, the CMD showed me one directory of the other msiexec.exe file. i followed the directory and found the msiexec.exe file in the folder. Then i copied back the misexec.exe file into the C:Windows\System 32 folder and the installation worked fine. No Errors, no "Interactive services Detection" messages. Everything working again as it was.

I am sorry. My mistake. If you put back the msiexec.exe file in System 32 Folder. The Message of Interactive Service Detection will pop up again and again. I will try to fix this in other way, and i will tell you later.

I understand, but i think it is the Nokia Multimedia Common Components installer that causes the error. Let me contact them, and lets see, what they will say. Thanks by the way for your replies, it feels good, when someone out there is really interesting in resolving problems. THANK YOU.

Ok guys. Finally it is solved. All you need is "MicrosoftFixit.ProgramInstallUninstall.Run". You can download it from: "http://support.microsoft.com/mats/Program_Install_and_Uninstall" after downloading this small application, run it and let it do it's magic. This software is from official Microsoft website and it is not from other location on the internet, so it is save.
