After setting execution policy to Bypass I'm still getting the following error. Can you please post detailed and accurate installation instructions?

import-module : Could not load file or assembly
'file:///C:\Users\Alex\Downloads\VMware.VimAutomation.Storage.Fling\VMware.VimAutomation.Storage.Fling.dll' or one of
its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

Did you also try unblocking the file when you first downloaded it from this site, windows sometimes blocks files downloaded from the internet and you have to right click the file and go to properties and then click the unblock button to unblock it, then unzip it and copy the files as part of the description.

Thats what worked for me.

import-module : Errors occurred while loading the format data file:
