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)

Maybe you don't have a user level PATH environment variable then? 2017-05-16 17:26:43
Maybe relevant: https://github.com/nim-lang/Nim/issues/5086 (How did this get fixed?)
