In Windows Vista, if you try to copy or install a file in the Program Files directory, the operating system will ask for security confirmation.
If you detach an attachment in Lotus Notes running on Vista to a secured directory, our testing indicates that it will not work and no dialog box pop-up to ask you to confirm you want to make a change in that directory.
Ytria tools' install process uses a basic Lotus Notes detach function (all the files are attachments in special notes). This means that Vista will prevent the Ytria installer from doing its job because the .exe files that need to be placed in the same directory as your Notes client will be blocked by the operating system (again, with no dialog box to warn you).
The special YtriaInstalRedirectNotesExeDir=<Temp Full Path> notes.ini parameter lets you choose another temporary directory to place these .exe files when you run any of Ytria's product installers. After that you can manually copy the files to your Notes.exe directory (where a pop-up dialog box will ask you to confirm).
Valid Values are:
A temporary full file path
NB: While this workaround solution works, our software development team is currently working on a permanent fix for Vista install issues.
