PowerCLI not picking up latest version of Python

[lazareth123]

Hey guys, 

I'm trying to inject a software raid driver into my esxi image and I'm trying to use a PS script which uses PowerCLI modules to do this but I can't get it to accept that I have the latest Python version and I keep getting this error: 

An unexpected error occurred:
Failed to initialize the VMware.ImageBuilder PowerCLI module because of error: Unsupported Python version. VMware.ImageBuilder supports Python 3.7.1 and higher.
Make sure that Python 3.7.1 or higher is installed and that you have set the path to the Python executable by using Set-PowerCLIConfiguration -PythonPath <executable_path>. See the PowerCLI Compatibility Matrixes for information on the Python requirements.

I've looked up so much online but I can't see what's wrong here. It's pointed to the correct directory for Python and the PATH is set correctly upon Python install.

Which PowerCLI version are you using?

[lazareth123]

thanks for the reply version 13. 

I've since got it to work by using Python 3.7.1 but I'm now getting this error while creating the iso: 

An unexpected error occurred:
[PEM: NO_START_LINE] no start line (_ssl.c:2471)

That sounds like the issue described in Custom ISO fails at Export-ESXImageProfile with a ... - VMware Technology Network VMTN

[lazareth123]

Yeah I saw that and uninstalled v13 down to v12 of PowerCLI but still the same problem 😞

It sounds like it's looking for a cert? Why would that be? I don't anything vmware setup so it's not like I have a cert for any vmware products. 

Also, merry xmas everyone and thanks for your help so far lucd!

Did you also try the procedure described in PowerCLI 13 update and installation hurdles on Windows

Well I followed that guide and went back to v13 and upgraded Python to 3.7.9 and what do ya know? it worked!
