Can't get the library working? Here are the most common resolutions to problems!
If you are looking at the components panel and can see different categories/views, but you cannot see any components in any view, you may have a connection error. Alternatively, you may be displayed the connection error below and not be able to view the components panel items at all.
Open the DbLib that you downloaded from the portal, if the error message mentions requiring 64-bit Microsoft Access - you do not need to install Microsoft access. Installing Microsoft Access will not fix the error.
If instead, you see the message "Connection Failed. Check your connection settings". There is an issue stopping Altium from connecting to the database server.
If you have found the component you require but the component panel can't find the footprint or symbol for the part, it is likely a new part that has been added since you last cloned the library files from GitHub.
If you are finding views in the component list starting with z_, these are the component tables and do not contain the columns Altium requires to work with the library. If you can see these tables, it means that your DbLib is out of date.
