jim and riyaz,
It seems we have an installer bit issue. For whatever reason, we are not reproducing any .NET errors here. However, the a11 installer is installing multiple versions of the DPS driver on top of itself which is never good. Check your device manager in Sound Video and Game controllers to see if this is happening to you.
To fix the multiple driver issue, uninstall DPS using the included uninstaller. Then right-click any remaining DPS drivers in the Device Manager and choose uninstall. Check the “remove driver files” box just to be sure.
Installing A11 from a blank slate like this seems to work fine.
Sorry for the trouble on this build, guys. It is critical for us to get the driver installation part bullet proof so we really appreciate your help.
