I bought the tool thru Steam and it was automatically installed and imported the songs from RS1 to RS2014, but I cant find the .exe anywhere.  I did a disk search from the root directory and it still did not show up anyplace.  Anyopne have an idea where it supposed to located at?  I was told I can use it to add DD to songs that don't have them.

The import tool (the thing you bought on steam to play RS1 on disc song on RS2014) and the rocksmith custom toolkit are too very different thing.

 

The toolkit you want to use to add DD is available for dl (for free!) here : http://customsforge.com/forum/60-download-rocksmith-toolkit/
