I mounted .iso file, but BCA doesnt allow me to continue.
1. i downloaded Boot Camp Support Software 5.1.5621 manually as you recommended me.
Was it downloaded using BCA and the second checkbox via a browser? Please see http://imgur.com/a/S0Lsi#0
Downloading via browser will not save a copy in /Library/Application\ Support/Bootcamp directory. If you use Safari, it will unzip the .zip file. If you use Firefox, it will let you save it as a .zip file. You can try putting this file the directory mentioned (normally it expects a .dmg) and then run BCA a second time and check all three boxes.
3. i cant install win 7 (screenshot above), because os x 10.10 doesnt recognize mounted .iso file win 7_64
If either method is successful for downloading the support software, BCA should also prompt you for the location of W7/W8 ISO, before it tries to partition your disk.
