32bit explorer.exe @ windows 7 64 bit

[lhotobb]

I was installing a theme and I accidently replaced my 64 bit explorer.exe with 32 bit explorer.exe in my Windows folder without creating a backup. I do not have any restore points. My screen got blank.

please help me

boot in safe mode(F8) with command prompt. type sfc/scannow.. if problem persist. do repair install.
