Error installing client: could not set file security

Hi,

When trying to perfom an upgrade from Lotus Notes client 5.08 to 7.01, program on c:\ and data on x:\ (personal network drive), the error "could not set file security on x:\notesdata\ returns. User rigths are correct on the network drive (are able to edit and create new files on the drive - (Novell network)).

The installation is from a msi-package, but tried installation from regular installation kit, no difference

Workaround is to install all on c:\ and edit notes.ini afterwards, and manually copy files to the network drive, no problems after that. This error only occurs on 1 of 40-50 users - any suggestions?

Thanks
