Install Failing in Windows 7 Ulitmate SP 1 Build 7601

Hi

I've used myrtille in the past on Windows 10 and it worked very nicely! Thank you so much!
I tried to install it now on a older machine which still runs Windows 7 as described in the subject. I haven't managed to install it due to some errors which are thrown during the install. The first error advises to check the log file which I did and the error is as follows:
"The term 'Enable-WindowsOptionalFeature' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again."

I did manually enable IIS in the Windows Features and rebooted that machine after enabling those features.

I manually downloaded the .NET prerequisite which is described in the doc and the installation doesn't proceed as it states that the same or a newer version of .NET has already been installed.

After the first error there are another few errors shows that the install.state files aren't found (which makes sense, because the install didn't complete...). The install then reverses everything he's done. Any advice on how I can rectify this issue? I did read in the doc that Win 7 OS is supported.....

Many thanks!

UPDATE: The Enable-WindowsOptionalFeature does not exist in Windows 7, only from Windows 8 and higher this cmdlet is available. Is there a previous release which doesn't use this CMD let in the installer script?

Yes, all releases prior to 2.8.0
