Windows 7: Windows 7 Installer

Thank for your help.

What programs are you having trouble with and what errors are you receiving?

I have a big problem with the Windows Installer , first the update of Microsoft Security essentials failed (mssefullinstall-amd64fre-fr-fr-vista-Windows 7.exe), secondly it was the Microsoft .net framework that failed (dotnetfx40_full_setup.exe), third I try to install the Apple iTunes that failed too (iTunes64Setup.exe).

I understand after one week that is a Windows Installer problem itself,, softwares that do no use Microsoft Installer install very well.

Since two weeks I am actively searching for a solution with no positive result.

Note :
1 - The windows installer service is working
2 - I tried to unregister the installer and re-register it, this did not work.
3 - When my problems began, I was using Microsoft Security essentials (now I am using Avira)
4 - The deletion of some registry key give no result
5 - I tried CCLeaner to correct registry error
6 - I tried Spybot in the case that the problem was causes by a Spyware
7 - I tried SFC /ScanNow


With previous versions of windows we could correct these problems by uninstalling and resinstalling windows installer. With Windows 7, the Installer is a part of windows.

Try running a Repair Install
