Windows7 system software cannot install prompts cannot access WindowsInstaller service

I do not know Win7 system users in the installation of software has not encountered the system appears "cannot access the WindowsInstaller service" prompts, especially when the MSI installation package is the most prominent issue. In fact, this problem is caused by the Microsoft WindowsInstaller Service, we are installing the extension named. MSI, you need to invoke the service when installing the package, so if there is a problem with the Windows installer service, the above error prompts appear.

The solution to this problem is very simple, as follows:

1. Start-All-attachments-command prompt

2. Right-run as Administrator

3. Enter the following content and return

Reg DELETEHKLMSOFTWAREMICROSOFTSQMCLIENTWINDOWSDISABLEDSESSIONS/VA/F

4. Reboot your Vista or Win7 system.

Some friends may say, this is not a registry operation, yes, this is through the command line to operate the registry (command-line programs require Administrator identity). Of course, you can also open Registry Editor at run input regedit.exe to find Hkey_local_machinesoftwaremicrosoftsqmclient windowsdisabledsessions

Remove this item and restart.

The method is simple, but very practical. If you encounter this problem, the above method can help you easy to handle, let you install the smooth sailing!
