Hej Ben,
Before i posted last time about the problem, i've tried excactly what you propose.
I tried to download and install from the download site on Arturia.com.
However the version there was yesterday v. 2.5.5.. And it did't solve anything.
I have followed your link. Now i see, that the version on the dowmload site is version 2.6..
As i saw that i thought that maybe things was allrigt now. So i tried to download and install from the new Arturia Software Center again. This time there was no trouble at all. So something must have been wrong with the Jupiter applikation download and install from the center, and now it is corrected. That's good.
The Arturia Software center is brand new. I like it's arrival. Much better way to download and install.
Just wish a way to select download folder. Maybe that okay too now. Will see. But guess i'll come.
Thanks for your time and trouble.
Kind regards
