The code is not saved, I have to enter it each time I launch the software.

This tip applies to Mac users only.

SOLUTION#1

Open the Finder, locate this folder:

<Mac>/Library/<instrument_name>/

Do a right-click onto, or [Cmd]+I, then select "Get Info".

Change the rights to "Read & Write" for every user on the machine.

Apply the changes by clicking on the gear icon: "Apply to enclosed items"

Now launch the software instrument, for the last time enter the authorization code. Relaunch it to ensure the problem has gone away.

SOLUTION#2

If still no luck, delete these folders:

<Mac>/Library/Arturia/<instrument_name>/
<Mac>/Library/Application Support/Arturia/<instrument_name>/

...then reinstall the instrument, launch and authorize it, have a quick test, then relaunch to check everything runs just fine now.

SOLUTION#3 (Analog Player vs. OS X Lion)

It looks like, under Lion, the installer is failing to create a required folder in the System's Library Folder. To fix it, do the following:

1. Open the Terminal application
2. To navigate to the Library directory, type:
   

   cd /Library/

3. To create a new directory called "Arturia", type:
   

   sudo mkdir Arturia

   (you'll need to enter your admin password to authorize sudo)
4. To create a new directory in the "Arturia" directory called "Analog Player", type:
   

   sudo mkdir Arturia/Analog\ Player

5. To assign open privileges to the new directories, type:
   

   sudo chmod -R 777 Arturia

Now launch the software instrument, for the last time enter the authorization code. Relaunch it to ensure the problem has gone away.

After running the application and authorization, 3 files should now appear in /Library/Arturia/Analog Player:

• plugin_demo.prefs
• standalone.prefs
• user_presets.prefs

If still having problems, try setting open privileges on /Library/Application Support/Arturia/AnalogPlayer:

sudo chmod -R 777 /Library/Application\ Support/Arturia/AnalogPlayer
