[Dumb Question - Download or Stream my a340 thoughts?]

Should I download (assume I can) my inibuilds a340 from the Marketplace to my local drive or keep using it in the streaming mode?

Thanks in Advance, I did check the FAQ first...

[Version Premium '24 1.0.5 download does not start]

Hi, after launching the iniManager, my a300-600R that was installed now shows as "not installed".  The "install" button is highlighted.  Due to the warning message saying I must uninstall my previous version of the a300-600r, I have not mashed the install button just yet. 

Please, what is the proper way to UNINSTALL my previous version of the a300-600R so I can install this new updated version.  Thanks in advance, all help appreciated.  MSFS2024 BTW
