On a customers' site I have installed regular labs extension manager, advanced module manager and some other regular labs extensions. It offers to "update" advanced module manger pro 9.6.4 to advanced module manger free 9.6.4. Extension manager has the download key and all the other extensions work as pro versions. Why does it want to downgrade advanced module manager from pro to free?

Thank you, it seems, this did work, while re-installing it via extension manager did not do the trick. Problem solved 🙂
