This happens when your Excel and Project applications are not part of the same Office version. You haven't said what version of MSP you are using, but I've never heard of a 2015 version for Windows. With no other complications, you may be successful by finding the excel.exe file in its home folder and copying it to the folder that contains your Winproj.exe file. Other complications can also get in the way. (They don't work for me.)
