This is a small update to 2.45. There was a port error that creeped back in for GetDrive_ macro in FileFunc.nsh. If you use that macro, you'd want to get this update. Also, I've noticed that some are staying with an older release of Unicode NSIS. If you are one of those who are happy with an older version of Unicode NSIS, please note that the 2.45 version has an important patch for Windows 7 support. So please update your installer with Unicode NSIS 2.45.1.
