  • VA 1.2.461 Frequently Not Responding – All Installed Libraries Show as “Not Installed”

    Anyone else running into this issue? After updating to version 1.2.461, VA keeps going unresponsive, and all my installed libraries suddenly show up as “Not installed.”

    Every time I try to reinstall or select “add existing library,” it just freezes and stops responding. I’ve tried restarting a few times, but it’s still happening.

    Anyone know how to fix this? It’s making it impossible to get anything done…


  • This issue still persists in the latest 1.2.483 version on macOS 15.2. I believe the problem lies with the VSLHelper utility, which appears incompatible with macOS 15.2 and later versions. Whenever you install a new library or add an existing library, it triggers the VSLHelper utility, causing the software to freeze.


  • When I try to install each library, I manually delete /Library/LaunchDaemons/at.co.vsl.viennaassistant.helpertool.plist every time. This allows me to complete the installation process. However, once I reopen Vienna Assistant, all libraries are still marked as "Not installed," even though I can use them in Synchron Player.


  • I hope this issue can be resolved in future updates, as it has been troubling me for three months. This is inconvenient for a user with the full Synchron series libraries. Keep it up, developers! 💪
