ExpanDrive has been updated to v7.2. This is a bug fix release that takes care of a number of small issues. It improves refresh performance of remote files as well as adds a native 64 bit binary for Windows. We are also now distributing a system-wide (multi user) MSI from our download page, suitable for bulk deployments.
You can grab it on the auto updater or over at our ExpanDrive 7 page.
