Windows7 system software can not be installed prompts can not access the Windows Installer service

I do not know if the Win7 system users have encountered the system when installing the software "can not access the WindowsInstaller service" prompts, especially when installing the MSI installation package this problem is most prominent. In fact, this problem is caused by the Microsoft Windows Installer service, we are installing the extension. The service needs to be called when msi installs the package, so if there is a problem with the Windows Installer service, the above error message will appear.
The solution to this problem is very simple, as follows:
1. Start - All - Attachments - Command Prompt
2. Right click - Run as administrator
3. Enter the following and go back Car
reg deleteHKLMSOFTWAREMicrosoftSQMClientWindowsDisabledSessions /va /f
4. Restart your Vista or Win7 system.
Some friends may say that this is not a registry operation, yes, this is the operation of the registry through the command line (command line program requires administrator identity). Of course, you can also open the registry editor by running regedit.exe and find HKEY_LOCAL_MACHINESOFTWAREMicrosoftSQMClient WindowsDisabledSessions
Delete this item and restart it.
The method is simple, but very practical. If you encounter this problem, the above methods can help you get it done easily, so that you have a smooth installation!
