Windows 7 – How to Run .msi Installer with Admin Rights

windows 7windows-installer

As in topic. I want to run .msi installer but I cannot install a program because it requires administrator rights. As for .exe files I know how to do that.

EDIT:
My problem is that I don't have 'Run as the administrator' when i righ-click, shift-click, control-click or anything. On .exe files I can see that option but not with .msi.

To circumvent this error, extract and double click on the:

Install_As_Administrator.reg

File that is included in the Install_As_Administrator.zip file distribution that can be downloaded from the top link on this page. This file will modify the Windows Registry to include the following information:
[HKEY_CLASSES_ROOT\Msi.Package\shell\runas]
@="Install &As Administrator..."

[HKEY_CLASSES_ROOT\Msi.Package\shell\runas\command]
@="msiexec /i \"%1\""
Once the Windows Registry has been modified using the Install_As_Administrator.Reg patch you can right click on any Windows Installer (*. msi) file and select the option Install As Administrator and the .msi file will run using elevated permissions (Administrator Permissions).

Windows – Run MSI files as administrator from a user account

.msi files can be executed with msiexec.exe, so in combination with the runas command, you could accomplish what your want:

runas /user:administrator "msiexec /i <path and filename of your msi>"

As a full-path to the file is recommended, it might need quotes around it and you need to escape them then with a backslash \:

runas /user:administrator "msiexec /i \"<path and filename of your msi>\""

Windows – How to make it so that all executables can run as administrator

Don't do it. Installers will usually report requiring elevation anyway. If they don't, Windows will probably ask whether the installation succeeded and give you an option to redo the process with elevation.

For incidental use, take half a second to right-click and run as admin, or type the executable's name in the start menu's search, then hit Ctrl-Shift-Enter. Elevate an already running program by clicking its icon in the taskbar holding Ctrl-Shift. Change the compatibility properties of a shortcut if a frequently run program always requires administrative rights. Suppress warning messages by turning off UAC if you're doing administrative stuff for a prolonged period, or log in using the Administrator account.

Don't do this by default. It might not answer your question, but it's good advice. As others have rightfully mentioned in caps and bold face, it is a major security issue, and I very much suspect anyone who is even close to capable of handling it, would know how to get elevation by default.

You will suffer all kinds of problems, even if you would never cause one yourself. Automated attacks are common and restricting an application's rights is a very effective way of keeping attackers out. Most computer owners I know who threw this security layer out the door had several botnets competing for CPU time.
