Topics: Configuration Issue

Recently I have the 'export an update' and 'manage catalog subscriptions' greyed out.

I searched some weeks for this.

cause:
Meta-Data for subscribed catalog has an error.

solution:
Delete the corrupt/wrong file(s) under \WSUS Package Publisher\Subscribed Catalogs\MetaData


I had only one file there from a first try to add a custom catalog.
