I want to register a key in the registry on the destination computer like this: [HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\AddIns\SikkerMail] "Description"="SikkerMail" "FriendlyName"="SikkerMail" "Loadbehavior"=dword:00000003 "Manifest"="C:\Program Files (x86)\Comendo Security\Sikkermail Outlook Addin\Sikkermail.vsto" When I enter this through the IS registry pane for the destination computer, everything is fine , the manifest installs upon launching Outlook. What I really want to do, is something like this: "Manifest"="%InstallDir%Sikkermail.vsto". but this just installs a key in the destination where the Manifest value is the same STRING as above, "%Installdir%" is not replaced by the full path as expected and the mainfest does not install. How can I obtain this? I've also tried to use [INSTALDIR] and the older version [TARGETDIR]. No result.
