Allow the Maker addon on Office 2007

Since PowerPoint 2007 does not support the "all users install" mode, the registry keys deployed in HKLM are not supported, it is then necessary to delete the following key to make the plugin work on the current user:

For Windows x86: reg delete "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\PowerPoint\Addins\Momindum Maker Add-on" /f
For Windows x64 : reg delete "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Office\PowerPoint\Addins\Momindum Maker Add-on" /f
