QTCore4.dll is missing error, need help

Having trouble with LMMS? Ask about it here.
I recently installed LMMS and launched the software. I closed it and came back to it to find this error, can I get some help resolving it?
Some more info on the operating system would be nice.

Windows ?
Along with Version of LMMS, 64 bit or 32?
