How can I install Allegro CL patches on Windows Vista/7?
Updating patches is a two-step process. First, a user typically calls the function (sys:update-allegro) to download all available patches, exits all lisps, then runs update.exe. Both of these operations result in the creation or modification of files in the Allegro directory. Windows Vista/7 has a security model that disallows installation of files into c:\Program Files\ if you do not have Administrator priviledges, which is where Allegro CL is installed by default. One solution, then, is to log in as an administrator when performing an update of your Allegro installation. This can be tedious and inconvenient. The second option is to use the “Run as administrator” right-menu option to temporarily elevate your priviledges. To install patches first navigate to the Allegro CL start menu and right-click on the image you’d like to start. Select Run as administrator. When you select Run as administrator you will need to answer in the affirmative to the User Account Control dialog boxes Vista
