Mango beta 2: error 80180048 - App Hub Forums
Look for a post from Rafael R.
Looks like you can use a V3 version of the Walsh tool to fix the issue (Read his instructions) or rerun the tool selecting the language packs.
While I only had English checked other languages were present (and selectable) on the device. Picked the correct languages on the walsh tool and ran his 'fix'
I didn't run the V3 tool so I can't attest if it works or not. Rerunning Walsh Tool V2 did and selecting all the language packs shown on my device under keyboard did resolve the issue and I now have 7392 installed!
Thanks Moirane as you directed me toward the right solution!!!
