UPX bad image on launch and notcompressible exception

Question

The script is super simple and works with no UPX.

import selenium
import scipy
import pandas as pd
print('Testing123')

Upon launch I get bad image

pyinstaller myfile.py --upx-dir=C:\upx394w --onedir

Does not work when launching exe, I am using windows 64bit.

pyinstaller az1.py --onedir –noupx (Az1.exe) [Works]

Now I run and get bad image. Only real issue could be: NotCompressibleException which could be issue but it appears to be compressed otherwise (full command line output):

Note worthy:

    upx: C:\Users\H0u\AppData\Roaming\pyinstaller\bincache01_py36_64bit\api-ms-win-crt-multibyte-l1-1-0.dll: NotCompressibleException

Okay, this is weird. This is common issue see here:

https://github.com/pyinstaller/pyinstaller/issues/1565

Deleting vcruntime140.dll fixes this. Will do further tests, but this is fixed by deleting that file causing issue (not sure if safe) but works.
