make sure you have the latest version of java 64 bit from here

if that doesn't sort it, press the windows key and R, an type %appdata% and press enter, then go into the .technic folder and rename the technic classic folder to something else. the next time you launch tekkit classic, the launcher will reinstall it for you.

you can then copy your saves from the "saves" folder in the tekkit classic folder you renamed to the new one.
