tup failed to build any nim source in windows

[Code Hz]

Hi, I'm trying to use tup to build some nim project
minimal repro:

1. download and install nim (by using choosenim)
2. create a empty nim source by touch a.nim
3. run tup init, and create Tupfile, with contents: `: a.nim |> nim c -o:a.exe a.nim |> a.exe`
4. run tup, and it will failed with Unable to read \.choosenim\current
5. even specify correct nim path in .choosenim path, still get similar error

I think it may related to dllinject/hook in windows
