Are you using the JAR or EXE?
"java64bit" is an incorrect version. A correct one is 7u4, 7u5 etc.
Change your launcher version, it's the Tekkit one, not the launcher one.
Get another antivirus.
Your description lacks so much detail it might as well be abstract art in text form. Elaborate.
By "clicking on technic launcher" do you run the JAR or EXE?
Try doing this instead:
1) Click on the start orb.
2) Type "cmd"
3) Ctrl-Shift-Enter
4) Type this in (TYPE, COPY/PASTE WON'T WORK): " java -jar %appdata%\.techniclauncher\technic-launcher-latest.jar "
Until you give me more details, 'tis all I can do.
