Unable to load qd3.dll

I have re-installed Quicken personal plus 2012 onto a different computer. (old computer died). When I attempt to access the backup of the QDATA.QDF file I receive an error message "Unable to load DLL: C:\Program Files (x86)\Quicken\convert03\qd3.dll". I am then prompted to re-install the product. I have this 3 times so far. Any solutions would be appreciated.
