In the last 3days (26 to 28 april 2013 ) I did a couples of mistake with the windows 64bit build for the molecular script. First off those are the manifest problem ( generate a 6034 error ). After that I forget to include the “molecular” folder in the zip file for making the installation working. Really sorry about that. I really need to make a automatic system for that instead to make it manually each time. Now it’s fixed and working fine on my side ! Thanks to Paul for reporting this problem.
