Enable run MSI files as admin

Tom DeMeulenaere Wednesday, October 17, 2018
Windows by default prevents you from right clicking MSI files and running them as an admin. This registry hack will allow you to get around that to install an MSI file as an administrator.

Create a .reg file with this info in it, and then double click on the file to insert it into the registry.


Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Msi.Package\shell\runas\command]
@=hex(2):22,00,25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,\
00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,6d,00,\
73,00,69,00,65,00,78,00,65,00,63,00,2e,00,65,00,78,00,65,00,22,00,20,00,2f,\
00,69,00,20,00,22,00,25,00,31,00,22,00,20,00,25,00,2a,00,00,00
