Can't install nim on Win 8.1

[Nugno]

Here is my problem:
    
    
    C:\nim-0.16.0>finish.exe
    Traceback (most recent call last)
    finish.nim(186)          finish
    finish.nim(130)          main
    registry.nim(44)         getUnicodeValue
    os.nim(153)              raiseOSError
    Error: unhandled exception: Can not find the specified file.
    

My exception is on russian so its might be not correct.

finish.nim(130): 
    
    
    let p = getUnicodeValue(r"Environment", "Path",
          HKEY_CURRENT_USER)
