App deployement Failed, invalid pointer error

Question

I am developing window phone 8 apps since November 2013 on window 8 pro. I am using window phone 8 emulator to test my apps. But from last one week every time I want to start emulator. the emulator takes 3, 4 minutes to show "The Window Phone os is Starting".
when I end the emulator there is pop up appear says "There is App deployment errors". in out put window i saw invalid pointer error. I stuck here searching Google a lot. but can't find an answer i need.

What Have I tried

• disable hyper-V from windows feature, restart computer and Enable Hyper-V. But not worked.
• Change no of CPU from 2 to 1. this also doesn't work.
• Disable my antivirus so that it can't stop Hyper-V to create VM. and start WP8 emulator

I am able to create VM. but unable to start window phone 8 emulator. I found only a few solutions out there. I tried everything I found But doesn't seems to solve problem. Anyone here for any suggestion what should I do to work my emulator again. Also I can't find why this error occur.

Update:-

anyone please answer or please suggest me what to do. should I update my sdk to 8.1? than this problem will resolved or not?

Answer 1

Disabling Hyper-V can result in a somehow fcked up configuration of the network profiles or VM Settings. I would recomend either deleting all Network Configurations in Hyper-V and all VMs OR reinstalling Visual Studio.
