Cannot build Hello World on Windows

I'm using MSVC2015 as well as
* rustc 1.41.0 (5e1a79984 2020-01-27)
* PyOxidizer v0.5.1-129-gd131051

After doing `pyoxidizer init-config-file pyap` and then going into `pyapp` to run `pyoxidizer run` I get the error

I verified that the following file which it seems its looking for does exist
`/c/Users/User/Documents/projects/practice/installer/pyapp/build/python_distributions/python.86a3260edabeed314c6f32a931e60dd097fa854b1346561443353e1bc90e3edd/python/install/Lib/site-packages/pip-19.3.1-py3.7.egg/pip/_internal/distributions/source/__pycache__")`

Start by reproducing `pyoxidizer init-config-file pyap` followed by `pyoxidizer run` on Windows with the reported MSVC, Rust, and PyOxidizer versions. Investigate the Python distribution path shown in the panic, especially the missing `__pycache__` directory, and compare it with the verified filesystem path. Done means the Hello World project builds without the panic.
