Troubleshoot problems with some software that is not installed under Windows 7

Remember that in the Vista era, many users often experience the problem of installing a software that prompts you to "not be able to access the Windows Installer service," especially when installing the. msi installation package.

In Windows7, such problems remain, mainly caused by Microsoft Windows Installer services. The installation package for the. msi is also required to invoke this service when it is installed, which can cause this error if there is a problem with the service.

The solution is also simple:

* Start-All-attachments-command prompt

* Right Key-run as Administrator

* Enter and return

Reg delete hklm\software\microsoft\sqmclient\windows\disabledsessions/va/f

* Reboot System
