Connection and using the LETSIGNIT application
2 URLs must be accessible for the application to work as expected:
All requests to these 2 URLs should not be subject to SSL decryption (if your security does 'Man-In-The-Middle' and/or SSL decryption and/or Java inspection) as the requests are formatted with a certificate specific to Letsignit infrastructures.
It is possible that "Google Analytics" URLs are also consulted as part of the "anonymous statistics tracking" concerning the application's utilisation.
%APPDATA% and %LOCALAPPDATA% folders availability: Read + Write.
Windows registry access for the user
.EXE application version - User session
Access to the Windows registry is required for the following keys:
HKEY_CURRENT_USER : (Read + Write)
-\SOFTWARE\Microsoft\Office\
-\SOFTWARE\Microsoft\Windows NT (if Outlook 2010 or 2007)
HKEY_CLASSES_ROOT : (Read only)
-\Outlook.Application\CurVer
-\CLSID\{00020D09-0000-0000-C000-000000000046}\LocalServer32
HKEY_LOCAL_MACHINE : (Read only for Google Analytics)

Version without automatic updates (.MSI / RDS)
When installing this version without automatic updates, three registry keys are created:
The first is in "RunOnce" in the HKEY_LOCAL_MACHINE section so that each user has the application running. After this execution the application resumes its usual behaviour and manages its "Run" in the HKEY_CURRENT_USER.
HKEY_LOCAL_MACHINE:
-\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce" Name="LetsignitApp" Type="string"
Value="[APPLICATIONROOTDIRECTORY]Letsignit App.exe --standalone-install"
The two following ones are used to create shortcuts: they are "KeyPath" keys that indicate to the computer that a component is installed.
They are deployed in the HKEY_CURRENT_USER of the user who installs the .MSI.
The first shortcut is on the user's desktop and the second in the programs.
HKEY_CURRENT_USER :
-\SOFTWARE\Letsignit\LetsignitApp" Name="desktopShortcut" Type="integer" Value="1”
-\SOFTWARE\Letsignit\LetsignitApp" Name="appShortcut" Type="integer" Value="1”
