Win7 can not install software processing method

Q: Windows7 system, I do not know what causes Office, kill soft, QQ and other software can not be installed, can only use the green version. The installation will prompt you for information about the Windows Installer service stop. How can this be solved?

A: This is generally due WindowsInstaller service is not started, or the corresponding file corruption caused by this service can not be started due. The correct solution is: first press the Win+R key combination to open the run dialog box, enter the execution command "services.msc" (without the outer quotes) to open the service manager, find the "Windows Installer service" and manually open it ( see picture 1). If the above method can not open the service, it may be that the corresponding file of the service is damaged. You can search and download the corresponding Microsoft Windows Installer on the Microsoft website, and then check the above method to ensure that the service runs normally.

A: Some large software, especially Microsoft software like Office, LiveMessenger, etc., need to support WindowsInstaller installation services, or can not install properly. The Windows Installer service is a software installation technology from Microsoft that automatically restores the computer to its original state after a failed installation. However, many software does not use this technology, and it does not need to be supported during installation. In addition, some friends may also encounter Windows Installer configuration errors when installing the program, and can also use Windows InstallerCleanupUtility to clear the program installation information, which can often solve the problem.
