When I run the installer for PotPlayer (http://get.daum.net/PotPlayer64/v3/PotPlayerSetup64.exe), it gets most of the way through the installation and then BSODs with a KERNEL_SECURITY CHECK_FAILURE. This is 100% repeatable and crashes in the same way each time. Just to be on the safe side, I have updated my video and WiFi drivers. WinDbg doesn't seem to point to any particular driver, but I admit that I am clueless when it comes to WinDbg. Hopefully someone here can shed some light!
I have attached the ZIP file produced by your log collector tool. Please let me know if you need any further information.
