Launcher update v2.4 download error.

The downloaded launcher update file is 2.03 MB.  System is windows XP with service pack 2, 32 bit.  The error message is: Installer integrity check has failed.  I downloaded the launcher update on another computor, same type of system with service pack 3.  It installed the update normally as far as I can tell.  So I tried tranfering the download to the computor with service pack 2, but I get the same error message when trying to apply the v2.4 launcher update.

Try just to download 1.01 patch, the launcher update is included there.
