As simple as that
I was about to, but the install warned me and I was not sure if I should ignore it or not.
But of course, a simple copy of the folder and test would work well

Thanks

Yes, making sure you select Portable Install in the installer.

Hi all,
Is there a "best practice" on how to upgrade a MM4 that is installed as "portable" on a USB?
I want to keep my library, settings, skins and addons (of course)

Is it as simple as installing to the same folder (over the old?)
