I have just tried installing version 0.100.2 on a clean Windows 10 with Python 3.7.4, both 32 bit.
Everything works fine except for installing the z-wave integration. The installation ends after a large number of lines with the KeyError: ‘WINDOWSSDKVERSION’.
Tried maually to execute pip3 install homeassistant-pyozw==0.1.4, but with the same result.
This might be an issue only related to Windows installations?
Almost certainly. Windows is not a primary platform for Home Assistant - there’s a reason the install guide sits under the message:
These guides are provided as-is. Some of these install methods are more limited than the methods above. Some integrations may not work due to limitations of the platform or because required Python packages aren’t available for that platform.
think Im now in the same boat here is there any way around this my whole house is zwave 2 
What’s your problem? How did you install Home Assistant? What version of Home Assistant are you on?
Having the same Problem using fresh install with version 0.102.3 and python 3.8 on windows 10
im using version 0.102.3 and python 3.8 on windows 10
this is the error im getting when i try to install pyozw-0.1.7 :

So, as mentioned in my reply to the OP, your choice to ignore the warnings and install on Windows is likely behind your problem.
