Downloading the SDK on to Windows 10 produces error about a corrupt or invalid msi

This is a known issue when downloading our installers on Windows 10. You should find that the files have in fact been downloaded and that you can still execute them.

If needed the following workarounds may help:

1. Turn off the SmartScreen filter temporarily in Control Panel under Security as described here.
2. Add https://developer.wacom.com as a trusted site in your internet options (assuming you downloaded the installers from there)

If none of the above helps please raise a Support Ticket.
