Client crash on launch (v2.7.1)

Hello,

My client crash on launch without any error message

This is what WP look in the taskbar when i launch him : http://i.imgur.com/SSZtw2p.png

Windows Anniversary (The one who broke CMD for CLI color syntax) x64
Intel® Core™ i5-4670K CPU @ 3.40GHz

Only Nvidia & Logitech service was running during try

What i actually tried :
- Remove whatpulse completely (also remaining key .. etc Sad )
- Remove WinPcap
- Ccleaner --> clean register
- Open regedit --> remove everything with search "whatpulse"
- Reboot
- Delete whatpulse.db & whatpulse.wpw & the complete folder
- Disable my antivirus
- Disable my firewall
- Install a old version (2.6.3)
- launch in admin mode
- Compatibility mode
- Install the 2.6.3 and update with your updater.exe without launching WP
- Disable my network protection
- Use my phone connection

Some note :
- I own and manage my own network
- I didn't install nothing from past 3 month execpt CCleaner to try to repair this issue
- Still work on my laptop with the same update
- WinPcap is not install i don't use network stats


I'm really out of ideas why this happen, any help is welcome

Thanks.
