Can't run new project in win64 mode, but win32 mode works fine

Question

I have recently reformatted my computer running Windows 8.1 and re-installed Delphi XE6 which was working fine prior to formatting the computer. Whenever i open up a new project and hit F9 (Windows 64 as target platform) i receive the following error:

Debugger Assertion Failure: "lastErr == WSAEINTR" in ..\\win32src\\wmcipc.cpp at line 294

Fatal error starting debugger kernel: 'Invalid debugger request'. Please save your work and restart RAD Studio XE6

I downloaded XE7 trial and ran into the same problem. I have done some google search but cannot find a resolution.

I guess there is some user access problem or a program blocking the debugger?
