A command to solve the problem that the software cannot be installed under Vista.

There are many users in Vista system who often encounter such problems. When installing a software, the system prompts “Cannot access the Windows Installer service”, especially in the case of This is often the case when installing the .msi installation package.

Actually until the latest Windows 7, this problem still exists, mainly caused by the Microsoft Windows Installer service. Installation packages ending with the .msi extension need to be called during installation, and this issue can occur if there is a problem with this service.

The solution is also very simple, Vista and Win7 are the same:

* Start - All - Attachments - Command Prompt

* Right click - as administrator Run

* Enter the following and press Enter

reg delete HKLM\\SOFTWARE\\Microsoft\\SQMClient\\Windows\\DisabledSessions /va /f

* Restart your Vista or Win7 system.

Of course, you may say that this is not the registry operation, yes, the registry is operated through the command line (the command line program requires administrator status). You can also run regedit.exe to open the registry editor and find

HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\SQMClient\\Windows\\DisabledSessions

Delete this item and restart.

The truth is the same. You can also make that statement a .bat batch file, then right-click to run as an administrator.
