      Lightroom 5.5 64 bit on WIndows 7. Tried to upgrade to Lightroom 5.7 over internet. Installer removed Lightroom 5.5 from my system but the 5.7 version failed to complete.  Error message says "Error 1335. The cabinet file 'Data1.cab' required for this installation is corrupt and cannot be used." Basically I now have no Lightroom at all.  Any Ideas of how to get 5.5 reinstalled or updated to 5.7?
