The only thing I can think of now is a software installed on your machine is causing the BSOD when trying to install WLM. I have a previous software installer not able to run or work after double clicking the installer icon. What I did was disabled my Antivirus(Avira) and installed it Offline. In your case, it might be ideally related. A Firewall, Antivirus or anything might be the cause. If you can specify much information on these softwares, you might be able to work around the problem if indeed you believe its only the WLM installation thats causing your BSOD. Another thing is to redownload WLM. It might also be a software glitch experience by other though not sure.
