Hello,
You shall update through Arturia Service Center (ASC). So open that application.
You will not see a V-Collection 9.2 mentioned anywhere in ASC, when you have updated. It will still show you have V-Collection 8 and 9, if they are to be found on your Arturia account under "My Products".
If you have installed V-COllection 9, then the updates should be ready to be installed in ASC. If there are'nt any updates, then they should allready be installed.
