Installed latest itunes of itunes only to find that videos, books, etc had been dropped. Tried to install earlier version (12.4.3.1)but installer said I had a later version. Ran system recovery, older installer then ran, but get the itunes library error. Any help? Thanks.
Running windows 7.
I probably misuse itunes. However I like it as a media center which you lose with the new method. Instead I went with removing itunes (see below) and reinstalled with installer mentioned above. I still got error message . Looked closer and saw it was an itl, not a dll. Found it lived in the itunes media directory. Out of desperation just deleted it. That seemed to work and then had to import everything into itunes, Thankfully was able to use the add folder option. After a couple of hours got it back together.
Photos seem to have changed, but still synced.
