Just wanted to put this here so I spare other people the frustration. If you install calibre first and Qt second, calibre overrides the system Qt libs. This happens because calibre's path is added to the system %PATH% variable before the path to the system Qt libs.

Kovid, you could solve this by putting your Qt libs in a special folder inside calibre's folder so that they don't end up on the %PATH%. This is a good idea for most windows programs anyway.

EDIT: Oh, and this was on Windows XP.
