Incoherent versions of ReportingServicesTools installed by the alternative installing methods

[maxbale]

In my Windows 10 PC, the versions of ReportingServicesTools installed by the 3 proposed methods in the Readme are not the same.
With
Invoke-Expression (Invoke-WebRequest https://raw.githubusercontent.com/Microsoft/ReportingServicesTools/master/Install.ps1)
and
Invoke-Expression (Invoke-WebRequest https://aka.ms/rstools)
the version installed is 0.0.6.6 in the folder \WindowsPowerShell\Modules

whereas with
Install-Module -Name ReportingServicesTools
the version installed is 0.0.8.0 in the folder \WindowsPowerShell\Modules

Can you tell me why this happens?
Why the latest version 0.0.9.0 isn't installed?
How can I force the version to install? (the -RequiredVersion parameters doesn't seem to work)
Can I force the installation folder to a different path?

Thank you

My PowerShell $PSVersionTable is:

The 0.9.0.0 version apparently had a problem with the build and didn't get pushed to the Powershell Gallery (according to #409 ). The project is languishing without official MS support.
