The Supplier Links have been broken in Circuit Studio.
When upgrading I got errors, so I did a complete uninstall and reinstall of Circuit Studio 1.5.2 (Build 30).
The suggested supplier link mechanism is Altium Part Provider, but it will not install.
Unable to download extension "PartsProvider_Altium_CS".
Error details: No versions found for product
"PartsProvider_Altium_CS" in AppRegistry.
