App-V: This Stack is Full of Crazy . . .

Scenario: A Computer (likely running Windows XP) with the App-V Client crashes with the

STOP: UNEXPECTED_KERNEL_MODE_TRAP Blue Screen (0x0000007F) during or immediately after installation of the App-V 4.6 client.

Arguments:
Arg1: 00000008, EXCEPTION_DOUBLE_FAULT
Arg2: 80042000
Arg3: 00000000
Arg4: 00000000

Unfortunately, this will likely happen during an installation or upgrade process. If it happens during an upgrade, it will result in a partially installed App-V state and no applications will be able to launch.

This may happen when one of the App-V file system drivers is conflicting with a driver used by the DeviceLock software. DeviceLock is a third-party application designed for Kiosks.

This can happen on any versions of DeviceLock earlier than 6.4.1.

The solution is to either remove DeviceLock or upgrade to a version compaitble with App-V 4.6 BEFORE installing the App-V 4.6 client.

NOTE: When you check out a dump caused by this issue one tell-tale sign will be the massive stack overflow so the stack trace will be full of crazy:
