25 Windows shell extensions need to be approved in order to be used by the
26 Windows shell for clarification read the following section from the
27 Microsoft Developers Network Library (MSDN) see
28 http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/shell/programmersguide/shell_int/shell_int_extending/extensionhandlers/shell_ext.asp

31 <MSDN>
32 Shell extension handlers run in the Shell process. Because it is a system process,
33 the administrator of a Windows NT system can limit Shell extension handlers to
34 those on an approved list by setting the EnforceShellExtensionSecurity value of the
35 HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer key to 1
36 (one).
37 To place a Shell extension handler on the approved list, create a REG_SZ value whose
38 name is the string form of the handler's GUID under
39 HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved.
40
41 The Shell does not use the value that is assigned to the GUID, but it should be set to
42 make inspecting the registry easier.
43
44 Your setup application can add values to the Approved key only if the person installing
45 the application has sufficient privileges. If the attempt to add an extension handler
46 fails, you should inform the user that administrative privileges are required to fully
47 install the application. If the handler is essential to the application, you should fail
48 the setup and notify the user to contact an administrator.
49
50 While there is no need to add values to the Approved key on Windows 95 or Windows 98
51 systems, there is no harm in doing so. The system will simply ignore them. However, there
52 is no guarantee that the key will exist on these systems. Your setup program must be able
53 to handle this case.
54 </MSDN>
55
56 We add the following entries to the respective registry key
57 "{C52AF81D-F7A0-4AAB-8E87-F80A60CCD396}"="OpenOffice Column Handler"
58 "{087B3AE3-E237-4467-B8DB-5A38AB959AC9}"="OpenOffice Infotip Handler"
59 "{63542C48-9552-494A-84F7-73AA6A7C99C1}"="OpenOffice Property Sheet Handler"
60 "{3B092F0C-7696-40E3-A80F-68D74DA84210}"="OpenOffice Thumbnail Viewer"
61
62 These shell extensions are implemented in the 'shell' project. We ignore registration
63 failures because of insufficient privileges. The reason is: On systems which restrict the
64 use of shell extensions by applying the aforementioned policy probably only people with
65 sufficient privileges are allowed to install applications anyway. On systems where the
66 use of shell extensions is not restricted registration failures because of insufficient
67 prviliges have no negative effect because the shell extensions will work anyhow.
