connect the double-click opening to other revit version

[Pliskin]

a colleague of mine connected time (do not remember how) rvt files to the open double click with revit 2012 because the client used that and always wanted to open the files with that version.now would like to return to open the files with revit 2014.
faceting:
- "tasto-dx on a rvt file -> open with -> default program" you can choose only autosk revit (that he has the icon of 2012 while from me he has the icon of 2014) and then ... not working
- "start -> control panel -> open a file type always with the same program" to the voice .rvt (autodesk revit project) is associated with autosk revit that with double-click always the same choice and then... not working
- "start -> control panel -> set default programs" there is no sign of autosk revit and there is no possibility to add other predefined programs and therefore ... not workingto solve the same problem in autocad that did not connect me a version that I wanted I used this method:>>> http://designandmotion.net/autodesk/mfg-pages/inventor/autodesk-dwg-launcher-wigged-out-fix/ <<<... changing the registry keys that define the program that opens the dwg files.
domanda:Is there a similar method to do the same in revit with rvt files (and rfa)?thanks to those who will help me.
