Details

Found from SANDBOX_FAILED_LAUNCH_KEYED telemetry. Chromium sandbox error code is 18 SBOX_ERROR_CREATE_PROCESS, which can only come from [1]. Windows error is 0x000002e4 ERROR_ELEVATION_REQUIRED. Haven't managed to reproduce artificially, but seems to be some strange interaction with UAC. We've seen 9 sessions with this on Nightly in the last 8 days, with 4 on two of those days. It'll be interesting to see how much this occurs on Beta, where my guess is people's UAC settings are more likely to be the default.
