### Administrator Privileges Explained

PC-DMIS versions earlier than version 2012 require that you run PC-DMIS as an administrator because some system settings (for things such as last probe used, wrist angles, and so on) were shared among all users on that computer. This required that these settings were placed in the LOCAL_MACHINE section of the Windows registry instead of in the CURRENT_USER section (for user-specific settings). Making changes to settings in the LOCAL_MACHINE section requires administrator privileges.

In PC-DMIS version 2012 and later, PC-DMIS's settings mechanism changed to only require Administrator access the very first time it runs at the end of the installation. From that point forward, standard user access is sufficient.

The PC-DMIS installer has a flag built into the setup executable (setup.exe) that requires the setup process to run with administrator privileges. If the current user has lesser privileges, the setup displays a prompt to provide a username and password of an account with administrator privileges.

Once installation finishes, the first time you run PC-DMIS, you must launch it with administrator privileges. If you mark the Launch PC-DMIS after the install finishes check box (as shown in the above image) when installation finishes, PC-DMIS does this automatically by passing the original privilege level of the installer onto PC-DMIS.

Note, however that if you do not mark this check box, you will need to explicitly right-click on the shortcut and select Run as Administrator as described in Step 6 below.
