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.

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:


File that is included in the 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:

@="Install &As Administrator..."

@="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).

A very convenient solution. +1 – Gangnus Feb 9 '14 at 15:34

Hitting Shift while clicking on the MSI and then running as a different user and putting in my credentials allowed me to run my MSI. I did this even though I was logged in with those credentials.

I believe you need to hold shift then right click on the msi (or application) to get the 'Run as Administrator' option. As detailed here:

This worked for me when the accepted answer (modifying registry) did not work. – Kristen Waite Mar 17 '15 at 19:57

Right click, Run as. Administrator -Easy as pie. By right windows SHOULD recognise its an installer and kick up UAC tho
