Yes that does help. Thank you very much. We fixed the registry on the PC in question and the problem is now solved.

Hi
Our application has the following scenario using Boost V1.0.52:
1) Process A writes to boost interprocess shared memory. The files appear at C:\ProgramData\boost_interprocess\...
2) Process A launches Process B
3) Process B attempts to read from shared memory but fails. It is attempting to read from: C:\Users\<username>\AppData\Local\Temp\boost_interprocess\...
This failure only occurs on one single Windows 8 64 bit machine out of many we have tested. On all other machines, the application works perfectly.
If you look in boost/interprocess/detail/tmp_dir_helpers.hpp: #if defined (BOOST_INTERPROCESS_WINDOWS) winapi::get_shared_documents_folder(tmp_name); if(tmp_name.empty() || !winapi::is_directory(tmp_name.c_str())){ tmp_name = get_temporary_path(); } #else if shared documents folder is not found, then the temporary path is used. The shared documents folder is found in the registry in the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Common AppData Hope it helps, Ion _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
