4.6.1 & 4.7 previews - Can't Launch on NVidia Shield

At the start of January I purchased an NVidia Shield tablet for Android development. I was able to successfully install it, the Android SDK and successfully run projects on it on two different PCs.

However, since buying a second NVidia Shield tablet for further development and moving to UE4.7 previews I am unable to launch projects on either tablet via either PC. The editor does recongise them as Shield Tablets in the ‘Launch’ options. I have also tried moving back to 4.6.1 and can no longer get them to launch either.

I’m using the TADP 3.04 provided by NVidia, and the Shield Tablet drivers it provides, as opposed to generic Google USB Drivers.

I was previously launching projects with BPs and custom assets, but I have also tried to cook and launch a blank project with no starter content and that fails as well.

I’ve attached a doc that includes the full cook and launch log for an empty project built in 4.6.1.link text
