BUG: MSDN Library Favorites Are Lost

• MSDN Library

SYMPTOMS

The MSDN Library favorites are lost.

CAUSE

There are three known causes of this problem:

• Installing a new version of the MSDN Library does not transfer existing favorites from the previous version.



• Launching the MSDN Library from a Visual Studio product can result in lost favorites. If the MSDN Library is still open when the Visual Studio product is closed, any favorites created during that session are lost. Closing the Visual Studio product forces the MSDN Library to close without providing an opportunity for it to save the new favorites.



• Deleting or corrupting the Hh.dat file erases favorites.

RESOLUTION

Currently, there is no way to migrate favorites from one installation of the MSDN Library to another; however, the favorites information is still preserved even when an MSDN Library is uninstalled. The previous version of the MSDN Library that contained the favorites can be reinstalled in order to see the favorites again. But to use these favorites in any other MSDN Library installation, the favorites must be manually found and re-created on that new version of the MSDN Library.

When using the MSDN Library launched from a Visual Studio product, always close the MSDN Library first before closing the Visual Studio product. This allows the MSDN Library to save the new favorites information normally.

If the Hh.dat file is deleted or corrupted, there is no way to recover the favorites. When the Hh.dat file is deleted, the MSDN Library creates a new one with no favorites information in it. When the Hh.dat file is corrupted, favorites may be lost or behave incorrectly, forcing you to delete the Hh.dat file, so it can be re-created.
