I just installed OpenVino on windows 10.
I installed all dependencies. Note that i *did* add the path to all users for all installations.
At first I installed Python 3.8 and got an error when trying to set environmental variables,
Unsupported Python bitness. Please install Python 3.5 or 3.6 (64-bit) from https://www.python.org/downloads
So I uninstalled Python 3.8. According to the requirements page, Python just has to be >3.5 (no mention of upper version limit).
On the python page they no longer have the installers for version 3.6. I installed version 3.7 and got the same error as above.
I also tried going to the next step, configuring the model optimizer, and that failed as well.
