Hi Jules,
Sorry that this seems to still persist on your end.
Here's what i would suggest you :
Please delete the Arturia Software Center preferences file, Here is how:
Windows :
- Go to this folder: C:\ProgramData\Arturia Software Center\user\
- Delete the "asc.pref" file
The folder may be hidden, if you do not find it with a simple search please try with the instructions described in the link below:

- Go to this folder : /Library/Arturia/Arturia Software Center/user
- Delete the "asc.pref" file
Once it's done, please try again.
If this persists, please try to also run it with a right click and by choosing Run as administrator.
Finally, try also to run it in Windows 7 compatibility mode through the properties menu when right clicking on it too and let me know how it goes.
Looking forward to hearing from you.
Best regards,
